Title

Turbo Tcm Coded Ofdm Systems For Non-Gaussian Channels

Abstract

The aim of this paper is to investigate the effect of impulsive noise on the performance of the Turbo TCM coded OFDM system. We construct a punctured parity-concatenated trellis code which functions as a turbo TCM code but with much lower complexity and explore their application in OFDM systems using 64QAM constellation to offer higher spectral efficiency. The conventional iterative bit MAP decoding algorithm is modified to catch up the corresponding impulsive noise statistical characteristics. The bit error rate (BER) performance of the TTCM coded OFDM systems over both AWGN channel and UWB channel with impulsive noise is evaluated through simulation. The study shows several essential requirements to achieve high data rate transmission for non-Gaussian channels. © 2006 IEEE.
