通信学中的QAM调制，这是一个比较经典的程序(QAM in communications )

直接序列扩频的缩写（DS-SS ） 二相相移键控（BPSK） matlab源代码(An acronym for Direct Sequence Spread Spectrum (DS-SS) two-phase phase shift keying (BPSK) matlab source code)

本代码可以实现CIC的抽取滤波功能，性能很好(This code implements the CIC decimation function, performance is very good)

high-end mathematical algorithm matlab source

此函数中详细介绍了如何现代功率谱估计法中的AR模型来妒忌信号的功率谱；(This function is described in detail how modern power spectrum estimation of AR model to envy the power spectrum of the signal )

BER of the VUS-MUMIMO-SM Uplink System - Rayleigh(BER of the VUS-MUMIMO-SM Uplink System- Rayleigh)

这个程序即可以读取XMl文件并转换成matlab结构体，也可以把matlab结构体转换成xml格式存放。xml是最被看好的数据存储方式，xml格式的通用性减轻了大家编写格式转换代码的痛苦。(This process that can read XML files and converted into matlab structure can also be put into matlab structure xml format. xml are the most promising way of data storage, xml format, reducing the U.S. generic format conversion code preparation suffering.)

This guide can draw a mandelbrot figure. In default values it calculates Z=Z^2+C for 20 iterations, where Z initally equal to zero and C has the values of every pixel created by meshgrid function(built-in). although mandelbrot equation is Z=Z^2+C you can change the degree of the equation between 1 - 50. higher number in iteration, points in axes gives better results in image besides more resulting time. to zoom an area of the figure you must aproximately choose the point and then change the center values to this point values then push Show Graph button. because of this is the first version there can be any lack of usage.
