摘要
Abstract
The demapping algorithm for the systems of hard-decision feedback based Bit-Interleaved Coded Modulation with Iterative Decoding (BICM-ID) calculates simply and has low complexity, so it is prone to be realized. The pre-dicision error bits are excessive in low SNR, so the error codes spread when they are feedback. In allusion to this problem, an improvement iterative demapping algorithm based on hard decision feedback is given, and its complexity to the primary algorithm is compared. Simulation results show that the proposed scheme have better performance both over AWGN and Rayleigh fading channels than the former system.关键词
