HLP A+ Modbus 标准通讯协议格式，上位机发送数据格式，正确时变频器返回数据格式(This bit will be set to logic 1 when the receive buffer has been read and contains no new information. If there is new information available in the receive buffer that has not been read, this bit will return to logic 0. RXBMT = 1 when in Master Mode.)

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.)

基于压缩感知的信道估计代码，有信道模型的建立和压缩感知信号的估计(Estimated based on compressed sensing channel code, the channel model)

Jake s无线通信信道模型仿真的Matlab源程序,采用SOS仿真方法。程序内容包括:时变信道的幅度的实部和虚部,幅度概率密度函数,自相关函数,功率谱密度。(Simulation of Jake s wireless communication channel model Matlab source code, using SOS simulation method. The program includes: the real and imaginary parts of time-varying channel amplitude, amplitude probability density function, autocorrelation function, power spectral density.)

pppoe常见故障分析,电信故障排除所需要的PPPOE知识(pppoe common fault analysis, telecommunications, troubleshooting knowledge required for PPPOE)

这是在PC端使用S7 M SC om M控制,在S - 200 C侧使用免费的PI端口通信,实现他们之间的信息交换,来创建一个简单的分布式控制系统。1 s7 - 200系列P LC自由端口通信方式 (This is in the PC End use of 7 M SC om M controls, in S- 200 PI C side using the free port Communication, realize the information exchange between their, to construct a simple Distributed control system. 1 S7-200 series P LC free port communication way)

说明：  SCMA系统中的PM-MPA检测，信道采用瑞利信道，迭代次数为6(For PM-MPA detection in SCMA system, Rayleigh channel is adopted and the number of iterations is 6)
