基于DNN网络的信道估计matlab仿真,仿真输出信道估计值的mse指标

1.算法仿真效果matlab2022a仿真结果如下： 2.算法涉及理论知识概要在信道变化迅速的系统中，通常依靠频域的导频子载波进行信道估计。导频子载波按照特定的规则插入到时频两维资源中。导频子载波处的信道响应可以通过最小二乘法(least-square，ls)和线性最小均方误差法(linearmi...

基于深度学习网络的5G通信链路信道估计算法matlab仿真

1.算法描述深度学习（英语：deep learning），是一个多层神经网络是一种机器学习方法。在深度学习出现之前，由于诸如局部最优解和梯度消失之类的技术问题，没有对具有四层或更多层的深度神经网络进行充分的训练，并且其性能也不佳。但是，近年来，Hinton等人通过研究多层神经网络，提高学习所需的计...

m基于RBF神经网络和BP神经网络的信道估计误码率matlab仿真

1.算法描述在无线通信系统中，从发射端发射的信号，经过直射、反射、散射等路径到达接收端。在ofdm系统中，为了获取更好的性能，需要进行信道估计获取信道的状态信息。ofdm技术虽然可以通过添加循环前缀的方式抑制多径效应产生的符号间干扰，但是却对高速移动产生的多普勒效应极其敏感。典型的信道估计方法包括...

m基于rbf神经网络和遗传算法优化的MIMO-OFDM系统信道估计算法matlab仿真

1.算法描述 MIMO-OFDM的信道估计：时，频，空三个域都要考虑，尤其是在空域，不同天线发射的导频序列需要相互正交，否则在接收端无法区分各个导频，造成导频污染，就无法正确地估计信道。正交的方法有很多，可以是时间上错开，在某个时间只允许某个天线发送。也可以在频率上错开。还可以让导频信号本身就是正交...
