说明：  此程序是基于广义最小二乘法，运用递推算法。(This procedure is based on generalized least square method, the use of recursive algorithms.)

使用MATLAB编程，用于仿真QPSK的解调

频率采样法设计低通FIR滤波器。有说明，有代码，简单易懂。(matlab LPF FIR)

采用3×3模板进行平滑滤波，去除噪声干扰(33 template smoothing filter to remove noise interference.)

噪声中正弦信号的现代法谱分析，采用了直接法、间接法、Bartlett法和Welch法，分别分析了不同窗长度、不同窗函数和不同信噪比对谱估计的影响。(Modern normal spectrum analysis of sinusoidal signal in noise adopts direct method, indirect method, Bartlett method and Welch method. The effects of different window lengths, different window functions and different signal-to-noise ratios on spectrum estimation are analyzed respectively.)

扩展卡尔曼滤波算法是滤波领域较为重要的方法之一。本滤波算法是典型的卡尔曼滤波应用问题。(kalman filter is a verry important filter.EKF is a better filter.)

说明：  该程序的主要功能是用于产生LFＭ线性调频信号(The program' s main function is used to generate LFM chirp signal)
