m基于机器学习MLP的OFDM信道估计误码率matlab仿真,对比LS和MMSE两种信道估计算法

1.算法描述信道估计器是接收机一个很重要的组成部分。在OFDM系统中，信道估计器的设计上要有两个问题:一是导频信息的选择，由于无线信道的时变特性，需要接收机不断对信道进行跟踪，因此导频信息也必须不断的传送: 二是既有较低的复杂度又有良好的导频跟踪能力的信道估计器的设计，在确定导频发送方式和信道估计...

基于DNN深度学习网络的OFDM信号检测算法的matlab仿真,对比LS和MMSE两个算法

1.算法描述在OFDM系统中，信道估计器的设计上要有两个问题:** 一是导频信息的选择，由于无线信道的时变特性，需要接收机不断对信道进行跟踪，因此导频信息也必须不断的传送: 二是既有较低的复杂度又有良好的导频跟踪能力的信道估计器的设计，在确定导频发送方式和信道估计准则条件下，寻找最佳的信道估计器结...
