Abstract

A technique is described for a better than 5 dB reduction in the peak to average power ratio (PAPR) of an OFDM signal. The optimal amplitude and phase of additional peak reduction carriers (PRC) is obtained using a codebook which is obtained using a search of all possible signal combinations.
