三次差分编码 和一次LZW压缩matlab源码，绝对正确，而且压缩率很高，80 以上，要是有不懂的，可以咨询我。(This is a realisation of lzw compression.If you have some problems ,you can contact with me.)

对无线通信信道中的衰落进行了仿真。考虑到无线通信中，频移及接受台移动速度等因素。 (Wireless communication channel for the decline of the simulation. Taking into account the wireless communications, the frequency shift and acceptance of mobile speed and other factors.)

Here s is a code for alamouti scheme having transmitter diversity! :) njoooy!

本matlab程序用共轭梯度法来求解多元模型的最小值（给出最小值和精度情况）(The matlab program conjugate gradient method to solve the minimum multivariate model (given the minimum and the accuracy of the situation))

时延估计算法 非常有用 非常适合初学者 其中包括了LMSTDE/ ETDE TEDGE 等多个不同的自适应时延估计算法(time_delay very helpful)

function ret = Int2Hex(var) Prints integer array to hexadecimal string varType = class(var) cast signness away: if ( u ~= varType(1) ) varType = [ u varType] var = typecast(var,varType) end nBits = str2double(varType(5:end)) if (64 == nBits) split 64 bit case into two 32 s cuz dec2hex doesn t handle 64 bit... varType(5:end) = 32 var = typecast(var,varType) end ret = dec2hex(var) if (64 == nBits) littleEndian = all(typecast(uint32(1), uint16 )==[1 0]) first = 1 + littleEndian second = 2 - littleEndian ret = [ret(first:2:end,:),ret(second:2:end,:)] end end

说明：  Model predictive control basic concepts

对信号进行取样，抽取，并将其与原信号对比(The signal sampling, extraction, and compared with the original signal)

可将输入的RGB图像转化为灰度图像！在Matlab环境下编程实现。(RGB images can be input into a gray-scale image! In the Matlab programming environment.)

基于simulink的现代通信系统仿真。很好的仿真源码！ ( Simulink-based simulation of modern communication systems. A good source of simulation! )
