OFDM Systems with Reduced PAPR
Abstract: To reduce peak to average power radio (PAPR) of orthogonal frequency division multiplexing (OFDM) system, flexible and distortion less methods like SLM (Selected mapping) and PTS (Partial transmit sequences) are very useful. The variation of OFDM signal amplitudes is very wide with high PAPR. Huge PAPR necessitates a DAC with sufficient dynamic range to handle the OFDM signals' large peaks. PAPR reduction has been demonstrated to save considerable amounts of …
