matlab讲义,包括教材，讲义，以及源代码。对学习很有帮助。(matlab lecture notes, including textbooks, lecture notes, and source code. Very helpful for learning)

这本电子书的名字是"基于matlab_simulink的系统仿真技术及应用"，同样对于学习通信的人士来说挺不错的，但是用的时候请下载超星阅览器(This e-book name is " based on matlab_simulink System Simulation Technology and Application" , on the same people who have to learn to communicate quite well, but when used, download SSReader)

又提供一基于生理的情感神经网络，包含杏仁体，丘脑，视觉神经等重要元素，可用于分类与预测，性能优越于SVM，BP(The use of neural network based on emotional physiology, contains important elements of the amygdala, thalamus, optic nerve, etc., can be used for classification and prediction, superior performance to SVM)

计算二维灰度-梯度直方图，很好用，特别好，啦啦啦(Calculate two-dimensional grayscale-gradient histogram, very good use, especially good, la la la)

说明：  锂电池simulink仿真模型，充放电电流、温度、电池初始电量为输入，电压、电流、SOC等参数为输出。(Lithium battery simulink simulation model, charge and discharge current, temperature, initial battery charge are input, voltage, current, SOC and other parameters are output.)

基于Matlab的CDMA通信系统下行信道的仿真_张兵(CDMA communication system simulation )

该文件可以读取相应格式的龙格库塔的数据，比较方便。(The file can read the corresponding format runge kutta data, more convenient. )

光伏电池simulink仿真模型，光伏电池IV和PV特性(Simulink simulation model of the photovoltaic cells, photovoltaic cells IV and PV characteristics)

注水算法是根据某种准则，并根据信道状况对发送功率进行自适应分配，通常是信道状况好的时刻，多分配功率，信道差的时候，少分配功率，从而最大化传输速率。本文运用matlab通过对注水算法在mino系统中的三种不同的情况下进行了仿真，比较出在小信噪比时，相同信噪比下利用CSI的功率注水算法获得容量优于未知CSI的平均功率分配算法；相同容量下已知CSI信噪比比未知CSI时的信噪比小3dB.当信噪比增大到一定程度时，功率注水算法所获得的信道容量将收敛到平均功率分配的信道容量。(Water flooding algorithm is based on certain standards, and according to the channel condition to adaptive allocation of sending power, usually is a good moment, channel situation more distribution power, channel is poor, less power distribution, so as to maximize the transmission rate. This paper USES matlab based on water flooding algorithm in Austin system of three different cases are simulated and compared in small SNR, under the same SNR use CSI power allocation algorithm for capacity is superior to the average power allocation algorithm of unknown CSI Same capacity known CSI signal-to-noise ratio than the unknown CSI small signal-to-noise ratio of 3 db. When the signal-to-noise ratio increases to a certain degree, the power allocation algorithm for channel capacity will converge to the average power distribution channel capacity. )

说明：  编程分别用jocabi迭代法求解方程。在一般情况下，Guass-Seide迭代法比Jacobi迭代法收敛要快一些，但这也不是绝对的，在木些情况下，Jacobi迭代法收敛，Guass-Seide迭代却可能不收敛(use matlab to deal with the equation )
