Abstract

Partial transmit sequence (PTS) is an attractive technique for PAPR reduction without distortion, but to obtain preferable PAPR performance it needs many inverse fast Fourier transforms (IFFTs), which results in high computational complexity. In order to reduce the complexity, modified PTS technique, with real and imaginary parts, separately multiplied with phase factors is considered in this paper. To reduce PAPR further the forward error-correcting codes (FECs) such as Golay codes and Turbo codes are employed in the modified PTS radix FFT, where, the PAPR is jointly optimized in both the real and imaginary part. The simulation results show that the combined FEC with modified PTS technique significantly provides better PAPR reduction with reduced computational complexity compared to ordinary PTS with FEC.
