Abstract

Abstract

The performance of Turbo Product Coded Pilot Symbol Assisted Modulation (TPC-PSAM) system is studied and a novel method to improve the performance of TPC-PSAM in Rayleigh fading channels by clipping the soft input information of decoder is presented in this paper. From the numerical simulation in different Rayleigh channels, it is concluded that the TPC-PSAM system with clipping soft information autperforms from 5dB to 8dB over the TPC-PSAM system at the bit error rate of 10-4.
