摘要 以城市无线广播电视信号传输系统常用的窄带Rayleigh快衰落信道模型为例,分析了常规MMSE-SIC检查算法的优劣,提出一种引入预测矩阵的改进MMSE-SIC检测算法方案,以满足不同通信环境的使用需求。仿真结果表明,该检测算法在不同通信环境下均有较好的误比特率表现,能达到改进算法的预期目的。 The core of MMSE-SIC detection algorithm,which is commonly used,is analyzed with the example of the narrowband Rayleigh fast fading channel model widely used in the urban wireless broadcast TV signal transmission system.An improved MMSE-SIC detection algorithm is proposed to meet the demand for the use of the harsh communication environment.The simulation results show that the detection algorithm under different communication environments has better low bit error rate performance and achieve the intended purpose of improved.
