调制信号的波形及其功率谱。。。很好用。。(The modulated signal waveform and the power spectrum)

本程序先生成一个“Blocks”信号，然后加上高斯白噪声，再用 db3 小波进行分解， 以说明三种取阈值方法和三种噪声标志对去噪性能的影响。(This procedure Mr. Cheng a " Blocks" signal, and then adding white Gaussian noise, and then ' db3' wavelet decomposition, to illustrate the three kinds of check-threshold method and three kinds of noise, signs of de-noising performance.)

Introduction to four classic articles OFDM

使用ESPRIT方法来进行谐波频率的估计(using esprit method to estimate the frequence)

可实现函数的产生，基本运算，时域频域分析(Generation function, basic operations, time domain frequency domain analysis)

包括TVD去噪（速度非常快），最小平方最优程序，用于稀疏频率分解，很好用。(Including TVD noising (very fast), the least-squares best program for sparse frequency resolution, very good use.)

Pf粒子滤波实现的目标跟踪程序，可实现针对非高斯噪声情况下的跟踪(Pf particle filter to achieve tracking procedures, can be non-Gaussian noise for tracking cases)
