This does convolution of two sequences in stepwise manner according to normal understanding. sigfold.m:-fips signal 1..and changes n accordingly. sigshift.m:-shifts flipped signal from left to right to cover all overlapping sigmulti.m:-multiplies two signals at each instant of overlapping convolution.m:-it finally calculates the sum of the product

Generating Multivariate Gaussian RV

用matlab实现灰度共生矩阵算法，并提取特征量(GLCM with matlab implementation algorithms, and the amount of extracted features)

自己设计的脉冲成形滤波器，采用matlab编码，并产生一个序列，输出经过成形后的波形(Pulse shaping filter design using matlab coding and generate a sequence, the output waveform after forming)

通过傅里叶变换的方法，对两个单频信号的相位差进行计算，信号相关性计算(Fourier transform method, the phase difference between two single-frequency signal is calculated)

This code simulates QPSK modulation on base band. This code has been written on Matlab and it will be very useful I think! :)

The standard optimum Kalman filter demands complete knowledge of the system parameters, the input forcing functions, and the noise statistics. Several adaptive methods have already been devised to obtain the unknown information using the measurements and the filter residuals.(The optimum standard Kalman filter demand 's complete knowledge of the system parameters. the input forcing functions. and the noise statistics.
