中文说明：
采用了小波去噪的思想，课程设计时编写的matlab程序代码，基于分段非线性权重值的Pso算法，搭建OFDM通信系统的框架，进行逐步线性回归，进行波形数据分析,最大似然（ML）准则和最大后验概率（MAP）准则，采用偏最小二乘法。
English Description：
By adopting the idea of the wavelet denoising, matlab code written in curriculum design, the Pso algorithm based on piecewise nonlinear weighting value, structures, OFDM communication system framework, the stepwise linear regression, waveform data analysis, the rule of maximum likelihood (ML) and maximum a posteriori probability (MAP) criterion, using the partial least squares.
