`
`ABSTRACT
`
`A system and method that scrambles the phase characteristic
`of a carrier signal are described. The scrambling of the phase
`characteristic of each carrier signal includes associating a
`value with each carrier signal and computing a phase shift for
`each carrier signal based on the value associated with that
`carrier signal. The value is determined independently of any
`input bit value carried by that carrier signal. The phase shift
`computed for each carrier signal is combined with the phase
`characteristic of that carrier signal so as to substantially
`scramble the phase characteristic of the carrier signals. Bits of
`an input signal are modulated onto the carrier signals having
`the substantially scrambled phase characteristic to produce a
`transmission signal with a reduced PAR.

`Phase Of The Carriers In A Multicarrier Communications
`System To Reduce The Peak To Average Power Ratio Of The
`Transmitted Signal," each of which are incorporated herein
`by reference in their entirety.
`
`FIELD OF THE INVENTION
`
`This invention relates to communications systems using
`multicarrier modulation. More particularly, the invention
`relates to multicarrier communications systems that lower the
`peak-to-average power ratio (PAR) of transmitted signals.
`
`BACKGROUND OF THE INVENTION
`
`2
`transmission signal is the ratio of the instantaneous peak
`value (i.e., maximum magnitude) of a signal parameter (e.g.,
`voltage, current, phase, frequency, power) to the time-aver(cid:173)
`aged value of the signal parameter. In DMT systems, the PAR
`of the transmitted signal is determined by the probability of
`the random transmission signal reaching a certain peak volt(cid:173)
`age during the time interval required for a certain number of
`symbols. An example of the PAR of a transmission signal
`transmitted from a DMT transmitter is 14.5 dB, which is
`10 equivalent to having a lE-7 probability
