wimax802.16e中的BTC编码仿真程序(WiMAX 802.16e in the BTC coding simulation program)

SPMS deal 模块，SPMS deal 模——(SPMS deal 模块)

D2D通信matlab仿真，基于matlab的D2D设备到设备通信系统模型仿真(Simulation of D2D Communication with MATLAB)

说明：  使用Simulink(或m语言)仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(m语言方式)，不是调用Simulink(或m语言)的已有编码、译码函数。并在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(Simulink (or M language) is used to simulate convolutional coding, and Viterbi decoding method is used to decode, in which the coding and decoding are all written by themselves (M language mode), rather than calling the existing coding and decoding functions of Simulink (or M language). In the additive white Gaussian noise channel, the relationship curve between bit SNR and BER is drawn.)

对BPSK进行了仿真，包括模块仿真和程序源代码仿真，我这边可以运行(For BPSK by simulation, including the module source code simulation and simulation)

北斗卫星接口文件 北斗卫星导航系统 空间信号接口控制文件 （测试版） (Beidou satellite interface file Beidou satellite navigation system space signal Interface Control Document (Beta))

此代码通过随机生成二进制码，对其进行二进制差分调制，以及加入高斯白噪声后对其解调计算误码率，绘制出其输入信噪比与输出信噪比的实验曲线及理论曲线的比较。(This code generates binary codes randomly, modulates them by binary differential modulation, demodulates them with Gauss white noise and calculates the bit error rate, draws the experimental curve and theoretical curve of their input signal-to-noise ratio and output signal-to-noise ratio.)

基于matlab-GUI制作的数字通信信号的调制仿真，包括时域、功率谱显示，仿真的调制方式有：ASK、FSK、PSK、QPSK、OQPSK、1/4piQPSK、8PSK、MSK，比较直观易懂，可供需要的同胞参考(this process mainly simulate varity of digital signal modulation,such as ASK、FSK、PSK、QPSK、OQPSK、1/4piQPSK、8PSK、MSK)

this is simply a report on the fading channel on different modulation scheme

一个与仪表通讯的上位机程序源码，采采用RS232通讯，协议为MODBUS (A host computer program source code with the instrument of communication, mining RS232 communication protocol MODBUS)
