`
`FUZZY AUDIO WIRELESS MUSIC SYSTEM
`
`This is a continuation-in-part of application Serial No. 10/027,739
`
`which patent application is pending.
`
`BACKGROUND OF THE INVENTION
`
`[0001]
`
`This invention relates to audio player devices and more particularly
`
`to systems that include headphone listening devices. The new audio system
`
`uses existing audio player device headphone jacks to connect a battery
`
`powered transmitter for wireless transmission of a signal to a battery powered
`
`receiving headphone.
`
`[0002]
`
`Use of audio headphones with audio player devices such as radio,
`
`tape players, CD players, computers, television audio and the like have been in
`
`use for may years. These systems usually incorporate an audio source having
`
`a headphone jack to which a headphone may be connected by wire and
`
`connector.
`
`[0003]
`
`There are also known wireless headphones that may receive A.M.
`
`and F.M. radio transmissions. However. these systems do not allow use of a
`
`simple plug in battery powered transmitter for connection to any audio player
`
`device jack, such as,
`
`laptop and desktop computers, portable compact disc
`
`players, portable MP3 players, portable cassette players and the like, for
`
`wireless transmission and reception of audio music for private listening to
`
`multiple users occupying the same space. Existing audio systems make use of
`
`electrical wire connections between the audio source and the headphones to
`
`accomplish private listening to multiple users.
`
`[0004]
`
`There is a need for a battery powered simple connection system for
`
`existing audio player devices, to allow wireless transmission to a headphone
`
`receiver that accomplishes private listening to multiple users occupying the
`
`same space.
`
`

`
`SUMMARY OF THE INVENTION
`
`[0005]
`
`The present invention is directed to FAWM (Fuzzy Audio Wireless
`
`Music) systems for coded digital transmission of an audio signal from any audio
`
`player device with a headphone jack to a receiver headphone using fuzzy logic
`
`technology. A battery powered digital transmitter may include a headphone
`
`plug in communication with any of the previously mentioned audio sources,
`
`laptop and desktop computers, portable compact disc players, portable MP3
`
`players, portable cassette players and the like. The FAWM system converts
`
`the audio music signal that may be supplied by the source, into a digital signal.
`
`This conversion takes place in the small battery powered transmitter that
`
`connects to the headphone jack of the source. The transmitter then adds a
`
`unique user code and transmits it to the battery powered receiver headphones
`
`where the fuzzy logic detector decodes only the unique user code to allow
`
`private listening without interference from other users.
`
`[0006]
`
`These and other features, aspects and advantages of the present
`
`invention will become better understood with reference to the following
`
`drawings, description and claims.
`
`BRIEF DESCRIPTION OF THE DRAWINGS
`
`[0007]
`
`Figure 1
`
`illustrates a schematic diagram representation of the
`
`FAWM system;
`
`Figure 2 illustrates a graph of the high and low bit fuzzy logic if-then
`
`part fuzzy set according to an embodiment of the invention.
`
`

`
`DETAILED DESCRIPTION
`
`[0008]
`
`The following detailed description is the best currently contemplated
`
`modes for carrying out the invention. The description is not to be taken in a
`
`limiting sense, but is made merely for the purpose of illustrating the general
`
`principles of the invention.
`
`[0009]
`
`Referring to Figure 1, a FAWM system 10 may include a battery
`
`powered transmitter 20 connected to a portable audio player or audio source
`
`80. The battery powered transmitter 20 may be connected to the audio source
`
`80 headphone jack 82 using a headphone plug 22. The battery powered
`
`transmitter 20 may have a transmitting antenna 24 that may be omni-directional
`
`for transmitting a coded digital modulated signal to a receiving antenna 52 of a
`
`battery powered receiver 50 that may be a headphone receiver. The battery
`
`powered receiver 50 may have headphone speakers 54 in headphones 55 for
`
`listening to the demodulated and decoded digital signal. The FAWM transmitter
`
`20 may digitize the audio signal. This digital signal has a throughput of
`
`approximately 1.4 Mbps, which may be determined by the analog to digital A/D
`
`converter sampling rate of 44.1kHz multiplied by 16 bit quantization. To reduce
`
`the effects of channel noise,
`
`the battery powered transmitter 20 may use
`
`convolutional encoding, and interleaving. For further noise immunity. spread
`
`spectrum modulation may be utilized. The battery powered transmitter 20 may
`
`contain a shift register generator (SRG) that may be used to create a unique
`
`user code. The unique user code generated is specifically associated with one
`
`FAWM user, and it is the only code recognized by the battery powered FAWM
`
`headphone receiver 50 of that particular user. The radio frequency (RF)
`
`spectrum utilized (as taken from the Industrial, Scientific and Medical (ISM)
`
`band), may be approximately 2.4 GHz. And the power
`
`radiated by the
`
`transmitter adheres to the ISM standard.
`
`[0010]
`
`Referring to Figure 1, the digital modulated signal from transmit
`
`antenna 24 may be received by receiving antenna 52 and then demodulated,
`
`

`
`decoded and deinterleaved in the battery powered receiver 50 headphones.
`
`The battery powered receiver 50 may utilize fuzzy logic to optimize the
`
`detection of the received user code.
`
`[0011]
`
`Each receiver 50 user may be able to listen (privately) to high
`
`fidelity audio music. using any of the audio devices listed previously, without the
`
`use of wires, and without
`
`interference from any other receiver 50 user.
`
`Because of the fuzzy logic detection technique used in the wireless digital audio
`
`system, user separation through code division may be achieved.
`
`[0012]
`
`The battery powered transmitter 20 sends the audio information to
`
`the battery powered receiver 50 in digital packet format. Each packet may
`
`consist of, at minimum, a start bit to indicate the beginning of a packet, the
`
`unique user code, the digitized audio information and a stop bit to indicate the
`
`end of a packet. These packets may flow to create a digital bit stream rate less
`
`than or equal to 1 Mbls.
`
`[0013]
`
`The user code bits in each packet may be received and detected by
`
`a fuzzy logic detector in the headset receiver 50. For each consecutive packet
`
`received,
`
`the fuzzy logic detector may compute a conditional density with
`
`respect to the context and fuzziness of the user code vector, i.e., the received
`
`user code bits in each packet. The fuzzy logic detector is the key component to
`
`the FAWM system 10. Because the fuzzy logic detector enables the battery
`
`powered FAWM receiver 50 to accurately detect the assigned user code in the
`
`presence of noise, which includes other FAWM users. Fuzziness may describe
`
`the ambiguity of the high (1 )/low (0) bit event in the noisy received packet. Note
`
`that the fuzzy detector may measure the degree to which a high/low bit occurs
`
`in the user code vector, which produces a low probability of bit error in the
`
`presence of noise. The fuzzy detector may use a set of if-then rules to map the
`
`user code bit inputs to validation outputs. These rules may be developed as if-
`
`then statements.
`
`[0014]
`
`The fuzzy logic detector in the battery powered receiver 50 utilizes
`
`the if-then fuzzy set to map the received user code bits into two values; a low
`
`

`
`(0) and a high (1). Thus, as the user code bits are received, the "if" rules map
`
`the signal bit energy to the fuzzy set low value to some degree and to the fuzzy
`
`set high value to some degree. See Figure 2. Due to additive noise each user
`
`code bit (bit energy x) may have some membership to a low and high as
`
`represented in Figure 2. Therefore, the if-part fuzzy set may determine if each
`
`bit in the user code, for every received packet, has a greater membership to a
`
`high bit representation or a low bit representation. The more a user code bit
`
`energy, x fits into the high or low representation, the closer its subsethood, i.e.,
`
`a measure of the degree to which a set may be a subset of another set, may be
`
`to one. Note that Figure 2 shows that -1 equals the maximum low bit energy
`
`representation and 1 equals the maximum high bit energy representation to
`
`illustrate that this design may utilize Manchester encoding/decoding schemes.
`
`[0015]
`
`The received user code input bit in each packet may be:
`
`x(i), where i = 1,2, ...., n is the set of all bits that make up the user
`
`code vector.
`
`X(c), where c = 1, 2,
`
`m represents each user assigned a unique
`
`user code.
`
`So user X(1) has bit code [X(1) x (2) .....x(n)] and user X(m) has bit
`
`code [X(1) x (2) ....x(n)] which is different from user X(1).
`
`[0016]
`
`Each x in X may activate a fuzzy "if" rule. The if-part sets may be
`
`conditional densities, so the fuzzy "if" rule activates to the degree p[x(i)|X(c)]
`
`p[X(c)], which is the probability of the user code bits x given the user vector X
`
`multiplied by the probability of X.
`
`[0017]
`
`The then-part fuzzy rule set may be indirectly dependent on the
`
`input bits x in X. The then-part set may be a weighted sum equal to p[x(i)]
`
`p[y|x(i), i = 1, 2,
`
`[0018]
`
`Which is the probability of the user bit vector x multiplied by the
`
`probability of y given the user bit vector x. Where y may be a number
`
`representation to define the correct user headset battery powered receiver 50
`
`

`
`given the input bit set x(i), I = 1, 2,
`
`[0019]
`
`The if-then rule parts that make up the fuzzy logic detector must be
`
`followed by a defuzzifying operation. This operation reduces the output fuzzy
`
`set to a single number that determines if the correct received user code bits
`
`within the transmitted packet have been detected. The defuzzifying operation
`
`may be implemented with the modal method, i.e., calculation of the value that
`
`has the highest membership in the fuzzy set. With the modal method a strategy
`
`of clarity may be applied in the event that some user code energy bit values
`
`have equally high membership. The clarity of a fuzzy set may be considered by
`
`weighting the conditional densities discussed previously.
`
`The weighting
`
`determines relative fuzziness of the user code energy bit
`
`(x)
`
`that gives a
`
`measure of the uncertainty of the unique user code vector. As a result, the
`
`fuzzy logic detector used in the battery powered headset receiver 50 greatly
`
`reduces the unique user code bit error probability. The fuzzy logic detector
`
`technique,
`
`combined with
`
`convolutional
`
`error detection and correction
`
`techniques, may enable the FAWM system 10 to operate in most any
`environment.
`
`[0020]

`While the invention has been particularly shown and described with
`
`respect to the illustrated and preferred embodiments thereof, it will be understood
`
`by those skilled in the art that the foregoing and other changes in form and details
`
`may be made therein without departing from the spirit and scope of the invention.
