PAPR reduction with low computational complexity for OFDM systems
The partial transmit sequence (PTS) technique has received much attention in reducing the high peak to average power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) signals, but its exhaustive search of phase factors causes high computational complexity. To solve this problem, a novel method based on optimization algorithm is proposed to reduce the complexity by searching the weighting factors suboptimally. The simulation results show that the proposed algorithm can not only reduces the PAPR significantly, but also decreases the computational complexity.
