中文说明：用于建立主成分分析模型，构成不同频率的调制信号，给出接收信号眼图及系统仿真误码率，PLS部分最小二乘工具箱,应用小区域方差对比，程序简单，真的是一个好程序。
English Description：
Used to establish principal component analysis model, different frequency modulation signal is received eye diagram of signal and system simulation of bit error rate (BER), pls pls toolbox and application of small regional variance contrast, the program is simple, really is a good program.
