`

`Written by leading experts in the field of wireless communications,
`OFDM for Wireless Multimedia Communicationsis a practical
`guide to planning, designing, and using orthogonal frequency divi-
`sion multiplexing (OFDM).
`It offers you a thorough overview of
`OFDM signal processing techniques, and provides a solid base for
`assessing the performance of wireless OFDM systems.
`
`Technical details of OFDM are provided, along with explanations
`of how OFDM signals are formed using the inverse fast Fourier
`transform, how windowing can limit out-of-band radiation, and
`how the cyclic extension mitigates the effects of modulation. You
`also learn how to assess the performance of OFDM-based sys-
`tems in terms of SNR and delay-spread tolerance.
`
`OFDM for Wireless Multimedia Communications contains a valu-
`able investigation of the applications of OFDM, including digital
`audio and video broadcasting and wireless ATM. Plus, it helps
`you understand IEEE 802.11, MMAC, and HiperLAN standards for
`wireless LAN.
`
`ISBN
`
`Richard van Nee, Ph.D., is a member of the technical staff at
`Lucent Technologies/Bell Labs in the Netherlands. He was among
`those who proposed the OFDM-based physical layer, which was
`selected for standardization in IEEE 802.11, MMAC, and ETSI
`HiperLAN. Ramjee Prasad, Ph. D., is Wireless Information and
`Multimedia Chair and Co-Director of the Center for Person-
`Kommunikation at Aalborg University. He is the author of COMA
`for Wireless Personal Communications and Universal Wireless
`Personal Communications, and coauthor of Wideband CDMA for
`Third Generation Mobile Communications, all published by Artech
