摘要：
This paper proposes a low complexity detection method for M-QAM (M-ary quadrature amplitude modulation) in spatial modulation (SM) systems. The new method utilizes the thought of constellation layering to modify constellation points search mode in QAM, which reduces the calculated amount significantly, and the total complexity will not increase with the size of constellation linearly. Simulation results show that the method can work well in high order QAM transmission systems. The novel method provides a significant reduction in computational complexity while keeping the near-optimal bit-error-rate (BER) performance.
