摘要：

In this paper, we propose a modified superposition modulation (M8M) and a new demodulation method based on decorrelation. Compared to the traditional superposition modulation (8M) signal, the constellation of M8M signal is asymmetric, which makes it hard to be demodulated by the uncooperative receiver. Traditionally, iterative processing is adopted for demodulation of 8M signal, and the computational complexity is amazing. Aiming at M8M signal, we proposed a new demodulation method based on decorrelation, the calculation complexity can be reduced remarkably.
