Patent ID: 7602697

Claim:
An orthogonal frequency division multiplexing (OFDM) system that is configured to implement an optimized tone reservation scheme, comprising: an OFDM transmitter; an OFDM receiver that is configured to receive OFDM signals from the OFDM transmitter over a communication channel, wherein the OFDM signals comprise a plurality of tones including data bearing tones that carry data and reserved tones for generating peak-to-average-power (PAPR) reduction signals; a channel estimation component that is configured to estimate communication channel information for the data bearing tones and also for the reserved tones; a tone selection component that is configured to determine tone selection information based on the estimated communication channel information; and a tone modification component that is configured to modify the selection of the reserved tones and the data bearing tones in the OFDM signals based on the tone selection information.
