设计一个低通滤波系统，任意输入三个频率使输入的信号中留下频率最低的 一个分量。(Designed a low-pass filter system, indiscriminate importation of the three input signal frequency so that left one of the lowest frequency component.)

基于FDTD算法，用MATLAB实现了波导色散特性的仿真研究(Based on the FDTD algorithm, implemented using MATLAB simulation of waveguide dispersion characteristics)

说明：  多用户检测 好多好多程序 MMSE 等等(Multi-user MMSE detection of all sorts of procedures)

通信原理常见信号 包括集中常用的nrz rz NRZ_D Manchester 等线路码型，还有其功率谱密度。(signals of the communication course,it s good to use.)

The file calculates and plots FM noise sidebands for a carrier. It also does sinusoidal modulation. This simple way of adding noise to a carrier is useful for simulation of PLLs. It turns out, though, that the mean of the randn function is not as close to zero as it could be, and this causes the fft to generate extra sideband energy, which makes it appear as if the noise is not what would be expected. This program gets around this by adding a fudge factor to the randn results to eliminate this problem. It took me ages to figure this out, I hope to reduce a similar effort for others

麻省理工学院的《matlab》学习的2010年课件资源，相当的不错，想学的不要错过，好难找的(MIT matlab learning courseware resources in 2010, quite good, want to learn not to be missed, so difficult to find)
