Title
PAR reduction of an OFDM signal using partial transmit sequences
Abstract
The peak-to-average power ratio (PAR) of an orthogonal frequency division multiplexing (OFDM) signal can be substantially larger than that of a single carrier system. Partial transmit sequence (PTS) combining can improve the PAR statistics of an OFDM signal. For PTS, the search complexity increases exponentially with the number of subblocks. We present a new algorithm for computing the phase factors that achieves better performance than the exhaustive binary search approach. We also investigate the effects of non-linear amplifiers on the performance of the new algorithm, including the power spectral density and in-band distortion.
