代码说明:

可以由任何插入的 pi-执行信道估计很多到所有的子载波 OFDM 符号与 speci¯c pe-荒漠化国际网 (块类型基于导频的信道估计) 或插入飞行员成每个 OFDM 符号 (梳式基于导频的信道估计)。自块类型导频的信道估计定期,职位飞行员所需的慢衰落信道的假设。后来,梳子类型试点信道估计,现已推出,以满足需求均衡时信道变化甚至在一个 OFDM 块。

    PIO 神经元网络从结构上可以分为输入层、隐含层和输出层三层, n 个控制量的 PID 神经元网络包含 n 个并列的相同子网络 ,各子网络间既相互独立 , 又通过网络连接权值相互联系。每个子网络的输入层有两个神经元,分别接收控制量的目标值和当前值。每个子网络的隐含层 由比例元、积分元和微分元构成(The structure of PIO neural network can be divided into three layers: input layer, hidden layer and output layer. The PID neural network with n control variables consists of N parallel identical sub-networks. Each sub-network is independent of each other and is connected with each other through network connection weights. The input layer of each subnetwork has two neurons, which receive the target value and the current value of the control quantity respectively. The hidden layer of each subnetwork is composed of proportional element, integral element and differential element.)
