利用matlab进行五点滑动平均法平滑处理(Using matlab five-point moving average smoothing method)

一个求解BUCK电路特征值的典型计算程序，非常适合学习混沌电路的初学者(BUCK circuit for solving eigenvalue of a typical computer program is suitable for beginners to learn chaotic circuit )

滤波器高斯噪声信道模型,信道模型的一种，matlab仿真源码(Filtered Gaussian Noise Model matlab code)

说明：  计算线性规划问题，以及简单的优化问题解决方案，matlab主要用于数学计算方面，是很简单的数学软件(Calculation of linear programming problems, and simple solutions for optimization problems, matlab mainly for mathematical calculations, is a very simple mathematical software)

说明：  几点说明： 1、source_main.m为主函数，qpsk.m和spread.m为子函数； 2、在matlab工程目录下运行source_main.m即可； 3、为方便大家理解，特以P-CCPCH信道的处理进行了举例，若大家认为资料有用的话请回帖， 我会将整个WCDMA下行信号源的matlab代码提供给需要的人； 4、为方便初学者学习，特提供了我自己开发时参考的3GPP资料，并在关键位置做了记号。 (Some explanations: 1, source_main.m main function, qpsk.m and spread.m as Functions 2, matlab project directory can be run source_main.m 3, to facilitate us to understand, especially for P-CCPCH channel processing of the example, if we consider the information useful, please Replies, I will put the WCDMA downlink signal source matlab code available to people in need 4, for the convenience of beginners to learn, especially when providing a reference to my own development 3GPP information, and in key positions in the mark.)

This simulation shows the effective SNR verse subcarrier number as a result of band pass filtering of the signal

以一个复合信号为例，做基本的维格纳分布（winger-ville distribution），有结果输出。(A composite signal, for example, to do basic Wigner distribution (winger-ville distribution), the outcome of the output.)

程序对4发4收系统进行V-BLAST检测算法的仿真。发送信号采用QPSK调制，信道为准静态瑞利平坦衰落信道，引入的噪声为均值为0的高斯白噪声，接收端分别采用ZF、MMSE、ZF-OSIC、MMSE-OSIC四种检测算法，根据其误比特率比较性能。(V-BLAST detection algorithm simulation program 4 of 4 admission system. Send signals using QPSK modulation, channel quasi-static Rayleigh flat fading channel, the introduction of noise with mean zero Gaussian white noise receiving end, respectively, ZF, MMSE, ZF-OSIC, MMSE-OSIC four detection algorithm based on its The bit error rate of the comparative performance.)
