【Abstract】 This paper put forward a new kind of soft demodulation algorithm for 16–APSK. Compared with the traditional hard decision algorithm,this algorithm can save storage space. Compared with the existing classic soft demodulation algorithm of Log–Max, this algorithm can reduce a lot of computational complexity. The simulation shows that the improved algorithm has better error rate than hard decision algorithm and almost no recession compared with the Log–Max algorithm.更多还原
