基于PCA和白化的数据预处理操作，PCA具有两个功能：维数约减和数据可视化；白化的目的是去掉数据之间的相关性。深度学习的一个主要工作就是数据的预处理(Based on PCA and data pre-whitening operation, PCA has two functions: dimensionality reduction and data visualization whitening purpose is to remove the correlation between the data. One of the main work is to study the depth of pre-processed data)

该程序完成一个16电平PAM数字通信系统的仿真，并测量了它的误码率。首先产生信息符号序列，该序列被当做4个信息比特一组，将16组符号映射到16个信息幅度。检测器计算距离，输出与真正传输的信息符号序列作比较，然后将差错计数。( This procedure completes a 16 level PAM digital communication system s simulation, and has surveyed its error rate. First has the message digit sequence, this sequence is treated as a 4 information bit group, maps 16 class symbols to 16 information scopes. The detector estimated range, the output and the true transmission s message digit sequence does compares, then counts the mistake. )
