Abstract: Data is transmitted during a transmission time interval using an available frequency bandwidth. Blocks of data to be transmitted at different power levels are identified. Multiple portions of the data blocks are distributed for transmission at different frequencies so that data blocks with higher power levels are distributed more toward the center of the determined frequency bandwidth than data blocks with lower power levels. The distributing of data block portions reduces the power of intermodulation products occurring outside the determined frequency bandwidth caused by radio frequency signals carrying the distributed data block portions fed through a non-linear power amplifier. It also reduces peaks in the power of the intermodulation products.

Abstract: A multi-carrier transmitter and transmission technique are described for transmitting payload data during a transmission time interval with reduced peak- to-average power ratio (PAPR). A multi-carrier modulator modulates subcarrier frequencies with payload data and provides a modulated signal for transmission during the transmission time interval. Excessive peaks in the modulated signal are extracted. The extracted peaks signal is transformed into the frequency domain to generate a peaks frequency spectrum which is processed using the frequency spectrum of certain subcarriers selected for reducing PAPR to produce a peak compensation spectrum. In one approach, that spectrum is transformed into the time domain before being modified by the modulated signal in the time domain to reduce PAPR. Alternatively, that peak compensation spectrum is modified using a modulated frequency spectrum provided by the modulator in the frequency domain and the result is then transformed into the time domain to produce a modified modulated signal with reduced PAPR.
