Demo of zero-padding DFTs for 4F7 course (lecture 2): Spectrum of a single complex exponential added together

调频立体声接收机模型 对相应的立体声解码过程进行建模和仿真。设左右声道的信号分别为1000Hz和2000Hz的单频测试信号。 (FM stereo receiver model for the corresponding stereo decoding process modeling and simulation. Set left and right channel signals were 1000Hz and 2000Hz single frequency test signal.)

说明：  function [Sx,f,alpha] = Sa(s,fs,M,N,read_f,del_f) 计算信号的循环谱 [Sx,f,alpha] = Sa(s,fs,M,N,read_f,del_f) 输入： s 序列 fs 采用频率 M 滑动频率窗长 N fft计算点数 read_f 可视频率（一般为载频的整数倍） del_f 可视频率间隔 输出： Sx 信号的循环谱 f 频率轴 alpha 循环频率轴(Cyclosationary Spectrum)

说明：  利用matlab实现双差算法添加、探测和修复GPS周跳(Detection of GPS cycle slip by DC algorithm)

说明：  预估校正控制，通过一种数值近似的计算方法不断逼近，从而实行控制计算。(A Predictor-Corrector )

各种功率谱估计算法!包括AR谱估计,BURG算法,YULE-WALK方程(various power spectrum estimation algorithm! Including AR spectral estimation, BURG algorithm, YULE-WALK equation)

国外MATLAB中使用PID控制的实验资料,里面包含了实验的所有源码和实验内容说明,非常有助于学习pid 控制的学习和理解(MATLAB abroad PID control of the use of experimental data, which includes all experimental and experimental content source that is very conducive to learning pid control of learning and understanding)

无线传感器网络加权质心自定位算法中加权质心算法仿真(Centroid algorithm simulation in wsn)

卡尔曼滤波是一种高效率的递归滤波器(自回归滤波器), 它能够从一系列的不完全包含噪声的测量(英文:measurement)中，估计动态系统的状态。 (Kalman Filter is a highly efficient recursive filter (autoregressive filter), It can complete a series of noise measurements included (in English : measurement). Dynamic System estimated the state.)

一段可以借鉴的增强图像效果的matlab代码，能达到很好的效果，可以参考。(Some can learn from the matlab code, can achieve good results, you can reference.)
