说明：  DL/T860系列文档完整版，IEC61850通讯模型(DL / T860 series document complete version, IEC61850 communication model)

can、RS422通信，定时发送串口所接收数据(RS422, can communication, the timing of the serial port to send data received)

Dynamic Subchannel and Bit Allocation in multiuser mimo-ofdma systems.

OP25 project, complete receiver and repeater source code for APCO25 digital trunking radio system

说明：  空间平滑music处理相干信号，相干信号的常用处理方法(Spatial smooth music processing coherent signal, coherent signal processing method)

叠加训练序列的最小二乘信道估计与最小均方误差均衡，QPSK调制，做了4次迭代估计的性能对比。(superimposed training, least squares (LS) channel estimation, MMSE equalizer, QPSK modulation, 4 times iteration.)

感觉这份代码中最有价值的应该是水声信道的建模，该源码来自美国 Parastoo Qarabaqi, Northeastern University, 2013其次其提供了基于l1范数下PCA处理算法，来对经由水声信道的信号进行处理给出误码率图，启动比较程序需要先使用信道生成函数对信号进行生成。(The most valuable part of this code is the modeling of underwater acoustic channel. Secondly, it provides a PCA processing algorithm based on L1 norm to process the signals passing through the underwater acoustic channel and gives a bit error rate chart. To start the comparison program, the channel generating function is needed to generate the signals first.)

16QAM信号最佳接收机，包括信号生成（+成型滤波）、上载波、过信道、下变频、匹配滤波、定时同步等过程(the optimal receiver for 16QAM, including signal source( shaped filter),modulation,AWGN channel, matched filter, timing sychnoization and so on)
