摘要：

In this paper, we propose new demapping scheme for the 16-APSK modulation, which reduces the computational complexity of demapping process. Compared to existing soft demapping methods, which calculate a decision metric for each constellation point, and hard demapping, which need a detailed look-up table, the new technique needs a short look-up table and no decision metric is needed to be calculated, thus reducing the complexity. The BER performance simulations reveal that this simplified demapping scheme does not cause any penalty on performance and retains same BER as those of existing techniques.
