摘　　要：针对高阶多输入多输出(MIMO)系统下,传统信号检测算法复杂度大的问题,结合禁忌搜索算法的基本原理,改进分层禁忌搜索算法,引入排序相消的思想,用于高阶MIMO检测。仿真实验结果表明,相比其他算法,在相同条件下,所提算法在误码率方面表现出更优的性能,尤其是在低阶调制信号、高信噪比环境下,该算法能避免出现瓶颈效应。Under the higher-order Multiple Input Multiple Output（MIMO）system,the traditional signal detection algorithm is very complicated,which combines the basic principle of Tabu Search（TS）algorithm and improvement of the layered tabu search Layered Tabu Search（LTS）algorithm,it introduces the idea of ordering cancellation for high-order MIMO detection.Simulation experimental result shows that compared with other algorithms,under the same conditions,the proposed algorithm has better bit error rate performance,especially under low-level modulation and at high signal-to-noise ratio,it performs better than other algorithms.
