Abstract

In this paper, we present some design methods for bandwidth efficient coded OFDM system. Multilevel turbo coded M-QAM scheme is investigated and some novel strategies are proposed to reduce coding complexities. An iterative multistage decoding with feedback between higher levels and lower ones is considered to be combined with Turbo decoding, which can improve the overall performance greatly. Several simulation results show that these schemes can provide substantial coding gains with high spectral efficiency.
