数字信号处理和滤波器设计，希望对大家有帮助。(Digital signal processing and filter design, in the hope that everyone has to help.)

说明：  matlaby源程序 关于OFDM的系统性能分析 (matlaby source on the OFDM system performance analysis)

最小均方算法是一种自适应滤波算法，这里的Matlab程序用于根据LMS最新均方识别一个线性噪声系统(LMS algorithm is an adaptive filter algorithm, where the Matlab program for the latest according to the mean square LMS noise system identification of a linear)

CONSX—这是一个主要子程序，调用其它于程序及输出中间结果 * !* CHECK—检查所有的点是否满足约束条件,对违背约束的点进行校正 * !* CENTR—计算中心点 * !* FUNC —目标函数，由用户提供 * ( PROGRAM COMPLEX PARAMETER(N=3,M=4,K=6) DIMENSION X(K,M),R(K,N),F(K),G(M),H(M),XC(N) INTEGER GAMMA OPEN(4,FILE= COMPDATA ) READ(4,*)ITMAX,IPRINT,ALPHA,BETA,GAMMA,DELTA READ(4,*)(X(1,J),J=1,N) IX=2097151 YFL=0.

求解振动信号的幅值的对数 对信号分析初学者有帮助( logarithm of the amplitude of vibration signal )

music change speed中，jiasu.m是让一首音乐旋律速度加快播放，jiansu.m是让一首音乐旋律速度减慢播放，两个情况下都不改变音乐的基调。(Music change speed, jiasu.m is to allow a faster melodic playing, jiansu.m is to make a musical rhythm to slow down play, the two cases do not change the tone of music.)

这是MATLAB程序设计的初步教程，希望对大家能有所帮助。(This is the initial MATLAB Programming Guide, in the hope that we can help.)

压缩感知的差分量化,此代码是基于块的压缩感知量化，减少了bit率，对压缩感知的量化有起步作用。(compressed sending ，bcs-spl-dpcm)

说明：  反正切函数的变步长算法,能实现反正切函数的变步长的仿真！(Arc tangent function, variable step-size algorithm)
