gradient descent in matlab

低通滤波,很好用，低通滤波器大家很常用，这是一个基于Simlink下简单的低通滤波器，适合初学者学习掌握(Low-pass filters are commonly used. This is a simple low-pass filter based on Simlink. It is suitable for beginners to learn and master.)

qpsk的调制解调源码，注释详细。功能正常。很适合学习调制解调的人.文件包含： qpsk_mod_demod.m(qpsk mod and demod procedure qpsk_mod_demod.m)

利用MATLAB对原始数据特征提取（数据降维）((Data dimensionality reduction of raw data feature extraction using MATLAB))

设计卫星绕地球运动的图象。要求：地球的直径≥5cm，卫星用五角星表示，卫星轨迹呈椭圆其中一部分轨迹被地球遮挡。(Design of the satellite around the earth in the image. Requirements: Earth' s diameter ≥ 5cm, with a five-pointed star, said the satellite, the satellite orbit was elliptical orbit by the Earth blocking part.)

强大的滤波器设计软件，实现低通、高通滤波，非常实用(Powerful filter design software, to achieve low pass, high pass filter, very practical)

几个有关通信系统的matlab程序,有关信号，包含：a,对抽样频率为90kHz的信号进行下抽样抗混叠滤波器设计的程序，b,信号抽样率转换的程序，c,通过补零内插对信号进行下抽样，分析抽样对信号频谱的影响的程序(Some matlab programs about communiction system,mainly about signal,a,program about filter to signal sampling without aliasing ,b,transfering signal sampling rate,c,zeros-added sampling,with its influence of phase-frequency。)

自己做的一个OFDM系统的波形信道仿真,分成各种模块实现，若有问题请朋友指正(OFDM system designed for waveform simulation using MatLAB，if there is any problem, please contact me.)
