in this folder we simulate the system of lorenz, vanderpol

下行信道加扰源码,matlab编写,方便对通信模型的仿真和学习(Downstream channel scrambling codes, matlab prepared to facilitate the simulation model for communication and learning)

说明：  主要是生成集合[n]的所有k-子集MATLAB代码(Generating set [n] of all k-subset of MATLAB code)

本文件是用matlab编写的俄罗斯方块，还挺好玩的哦(This document is written using matlab Tetris kinda fun!)

说明：  这是一个有关frft的matlab的程序，请好好利用吧(a programm about frft,please take full use of it)

本程序仿真了AWGN信道下，采用DS扩频对bpsk信号的影响，扩频码采用walsh码，扩频因子16； 接收端进行rake接收，然后分集合并，比较了三种分集方式对误码率的影响 从图像可以看出在扩频因子较高的情况下，最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16 Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)

Minimizes a function with the method of simulated annealing

本代码为配电网经常使用的前推回代计算潮流的matlab程序(The code for the distribution network is often used to calculate the trend of forward and backward substitution matlab program)
