CDMA

说明：  这是射线信道模型的代码。里面有多个m文件(This is the code for the ray channel model. There are multiple M files in it.)

本文作的工作是利用信号仿真器仿真GPS数字中频信号，并借助这些仿真信 号完成对GPS信号的捕获和跟踪性能的研究。(This article is for the use of GPS signal simulator simulation digital IF signal, and make use of these simulation signal completion of the GPS signal acquisition and tracking performance study.)

This is ieee paper describes OFDM radar implementation, good for study and understanding

说明：  实现了神经网络PID算法的编程,通过神经网络在线调节PID参数(MATALB BP PID sfunction)

说明：  天线模型建立和分析的matlab程序，包含各种基本天线种类。(The matlab program of antenna model establishment and analysis includes various kinds of basic antennas.)

在Matlab环境下用于计算CRC16的代码，本原多项式为X16+X15+X2+1，并提供测试文件。(In the Matlab environment for the calculation of CRC16 code, the primitive polynomial is X16+X15+X2+1, and provide the test file.)

详细的讲述了linux的ip/tcp通信部分的协议栈，对开发很有帮助(Linux detail of the ip/tcp communication part of the protocol stack, on the development of useful)

说明：  数字通信系统的仿真，全matlab代码，实测可用(Digital communication system simulation, full matlab code, measurement available)

这是看完一本通信仿真手册后我自己写的一点程序，包括ASK FSK PSK的调制和解调程序，不过是比较简单的 ，因为用了公式的()

快衰落多输入多输出信道中，无信道状态信息的酉空时调制。属于信道发射和接收两端均无信道状态信息的非相干空时码。程序包含一个主程序和一个酉空时信号产生子程序，并给出误比特率。(Unitary space-time modulation without channel state information in fast fading MIMO channels. It belongs to the incoherent space-time code with no channel state information at both ends of the channel transmitting and receiving. The programs include a main program and a unitary space-time signal generation subroutine, and gives the bit error rate.)
