该程序适合于强散射环境下，并分析了收发端分别有nr和nt个天线情况下的系统容量。(In this programe a highly scattered enviroment is considered. The Capacity of a MIMO channel with nt transmit antenna and nr recieve antenna is analyzed.)

巴特沃斯滤波器，主要实现的是低通信号，此功能模块的低通曲线很符合理想的幅频特性。(Butterworth filter, the main achievement is low traffic numbers, the low-pass curve is consistent with this function module ideal frequency characteristics.)

说明：  基于matlab中guid平台设计的一个卡尔曼滤波器，该滤波器可以用来供大家学习如何设计现代数字滤波器(Matlab-based platform in the guid of a Kalman filter that can be used for everybody to learn how to design a modern digital filters)

使用Matlab语言完成《数值计算方法》中的Romberg（龙贝格）积分公式，程序可以根据用户输入的积分上下限、误差容限及表达式实现Romberg积分。(Using Matlab language to complete " numerical methods" in the Romberg (Romberg) integral formula, the program based on user input limits of integration, error tolerance and expression implementations Romberg integration.)
