51MODBUS从机程序源码希望对有用的人有用，，(51MODBUS,welcom to here,thank you very mouch.)

对NOMA下行链路的用户和信道功率分配的优化(Energy-Efficient Resource Allocation for Downlink Non-Orthogonal Multiple Access (NOMA) Network)

仿真MIMO信道容量与信噪比和发收天线数目的关系，(Simulated MIMO Channel Capacity)

雷达LFM（线性调频信号）仿真程序，包括信号生成，脉冲压缩以及实际FLM回波信号处理。(radar LFM signal Processing)

数字通信中的16QAM映射，采用格雷码编码，包括星座图的显示，简单明了清晰，由此可以退出64,128QAM的matlab编码(Digital communication 16QAM mapping, the use of Gray coding, including the constellation display, simple clear, it can be out of the 64,128 QAM matlab code)

说明：  PCM编码译码的matlab代码，设一个输入量，对其进行通信原理仿真。(The MAT code of the PCM code decoding, set an input quantity, and simulate the communication principle.)

串口或者以太网口的103规约的端口测试和规约解析软件，解压即可用。(iec103 TEST)

说明：  CCSDS推荐的LDPC编码方案，一系列参考标准，很好哦！(CCSDS recommended LDPC coding scheme, a series of reference standards, very good!)

研究信道噪声对M-ary QAM的影响，适合数字通讯从业者(Effect of channel noise on M-ary QAM in)
