Communication

说明：  一些时反的例程和其他代码，mat文件是信道信息(The Mat file is the channel information. There are some examples of the Time Reverse and communication system.)

the pdf entitled The Modulo Lattice Channel The Key Feature in Precoding is attached

信道均衡的讲义，将均衡讲的出神入化，非常之好(Channel equalization of the handouts, will talk about the superb balance, very good)

ZigBee tutorial, good for a short finalt graduate course work

说明：  利用伪随机序列作为发送信号，经过信道，产生了频偏和相位偏移，利用数字锁相环的原理实现对信号的频率估计和相位估计，实现信号的载波同步。(The frequency offset and phase offset are generated by using pseudo-random sequence as the transmitting signal through the channel. The frequency estimation and phase estimation of the signal are realized by using the principle of digital phase-locked loop, and the carrier synchronization of the signal is realized.)

基于阵列信号处理的跳频信号盲检测和参数盲估计matlab 仿真(Matlab simulation of blind detection of frequency hopping signal based on array signal processing)

在STM32上实现单线多个DS18B20实验，通过串口监测8个DS18B20测量的温度，芯片信号等(Several DS18B20 experiments on single line are implemented on STM32, and the temperature of 8 DS18B20 measurements, chip signal, etc. are monitored through serial port)

产生16QAM基带信号，成型滤波通过AWG信道，接收端得到误码率和星座图。(The 16QAM baseband signal is generated, the shaping filtering is passed through the AWG channel, and the receiving end obtains the BER and constellation diagram.)

说明：  产生数字基带信号，加入AWGN高斯白噪声在信道中传输，检测出原始基带信号，并绘制理论和仿真误码率曲线(The digital baseband signal is generated and transmitted in the channel with AWGN white Gaussian noise. The original baseband signal is detected and the theoretical and simulation BER curves are drawn)
