Abstract

In this paper, we present an efficient soft de-mapping method for M-ary APSK modulation based on hard decision thresholds (HDT), which significantly reduces the computational complexity compared with the maximum likelihood detection (MLD). Furthermore, bit error rate (BER) performance of several soft de-mapping methods combined with LDPC codes are provided. Simulation results reveal that the proposed method largely reduces the computational complexity with nearly the same performance to MLD.
