基于matlab的mimo-OFDM仿真程序(Based on the mimo-OFDM matlab simulation program)

上位机与三菱PLC之间进行TCP/IP通讯(communication between PC and PLC)

mqtt-python收发，里面有几个例子，对于topic的分类，mqtt的连接，收发等！(Mqtt transceiver in python!)

(1)建立DQPSK调制和解调 SIMULINK仿真模型，评估其在AWGN信道和瑞利衰落信道下的误码率性能（画出信噪比变化时的误码率曲线）； (2)基于（1）建立的SIMULINK仿真模型，分别在AWGN信道和瑞利衰落信道下发送一个实际音频文件，在接收端实时播放出来((1) the DQPSK modulation and demodulation SIMULINK simulation model is established to evaluate the bit error rate performance under the AWGN channel and the Rayleigh fading channel (the bit error rate curve when the signal to noise ratio changes). (2) based on the (1) established SIMULINK simulation model, a real audio file is sent under the AWGN channel and the Rayleigh fading channel respectively, and it is played on the receiving end in real time.)

说明：  该资源为应用GNUradio工具，对USRP的开发，主要实现了频谱感知，以及根据频谱感知的结果进行ofdm通信的功能(This resource is the development of USRP using gnuradio tool. It mainly realizes the function of spectrum sensing and OFDM communication according to the result of spectrum sensing)

Polar码学习。实际测试BER特性基本与文献Kai Niu;?Kai Chen;?Jiaru Lin;?Q. T. Zhang, ?Polar?codes:?Primary?concepts?and practical decoding 　　algorithms,IEEE Communications Magazine 一致(this is about polar code)

说明：  这是一个C语言实现的一阶到六阶的IIR滤波器程序,用于TI TMS320C5416 Texas 工具(This is a C-language-implemented first-to-sixth-order IIR filter program for the TI TMS320C5416 Texas tool)

There were downloaded documents wich can be very useful for those who exploring Wireless Sensor Networks. There given all the information and scripts to creat or build the model you need.

DL/T645-2007清晰文本版，可以CTRL+F(DL/T645-2007 clear text version, you can CTRL+ F)

此程序实现了AWGN信道下的模拟调制解调，用的是matlab平台(This program implements the analog modulation and demodulation under the AWGN channel, using the MATLAB platform.)
