lfm及其模糊函数

Windows系统下Modbus RTU协议从站，VB.net开发，可以直接支持研华系列采集模块的源代码(Windows systems, the Modbus RTU protocol slave, VB.net developers can directly support the of Advantech series acquisition module source code)

This includes how to protect the speaker using matlab functions.

一个很小和天线计算程序,我觉得非常实用,发上来与大家分享()

包含twincat2串行通讯等必要的库文件,(Beckhoff PLC communication program in the no- protocol on the platform of TwinCAT)

用C++语言封装的MODBUS通信协议 可直接在工业中用于RS485 与232的通信(modbus communication is demonstrated by c++ language)

说明：  实现了polar在BEC信道下的编译码，画出了误码率图像(The encoding and decoding of polar in BEC channel is realized, and the bit error rate image is drawn.)

performance evaluation of reactive and proactive protocols. the performance is evaluated with respect to throughput over TCP and UDP connections types

对移动通信中的多径多普勒频移进行详细的仿真，对学习这个的朋友有极大的帮助(Of mobile communication in multi-path Doppler frequency shift to conduct a detailed simulation study of the friends of great help)

OMP重建一维二维信号，Matlab源码，中文注释(OMP reconstruction of one-dimensional two-dimensional signal, Matlab source code, Chinese comment)

说明：  6. 在三条径的瑞利信道中，对于OFDM： (1) 请设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真。画出比特信噪比与信道估计均方误差的关系曲线和比特信噪比与误码率的关系曲线。 (2) 设频率已同步，请设计OFDM一种具体的采用循环前缀进行时间同步方法，用Simulink进行仿真，画出比特信噪比与捕获概率的关系曲线。 (3) 设时间已同步，请设计OFDM一种具体的采用循环前缀进行频率同步方法，用Simulink进行仿真，画出比特信噪比与频率同步误差的关系曲线。(6. In the three-path Rayleigh channel, for OFDM: (1) please design a specific navigation-assisted channel estimation method and use Simulink for simulation.The relation curves of bit signal-noise ratio and channel estimation mean square error and the relation curves of bit signal-noise ratio and bit error rate are drawn. (2) if the frequency has been synchronized, please design a specific method of time synchronization using cyclic prefix in OFDM. Simulink is used for simulation to draw the relationship curve between bit-snr and acquisition probability. (3) if time has been synchronized, please design a specific method of frequency synchronization using cyclic prefix in OFDM. Simulink is used for simulation to draw the relationship curve between bit signal-to-noise ratio and frequency synchronization error.)
