基于matlab的PN码的同步仿真，包含详细代码，可以直接运行(Matlab based PN code synchronization simulation, including detailed code, can run directly)

LTE系统中信道的加扰调制部分,子载波建立的必要过程( LTE, modulate ,scrambing,16QAM,64QAM,QPSK,)

说明：  实现了64qam，16qam和QPSK的误码率仿真(The bit error rate simulation of 64qam, 16QAM and QPSK is realized.)

说明：  STM32对接ESP8266的驱动,测试MQTT通讯和测试TCP通讯(STM32 TO ESP8266,test MQTT communication and test TCP communication)

用于监控PLC，针对的是modbus协议(monitoring PLC with modbus protocol)

说明：  cclink -ie 通讯手册 ，需要的朋友可以看一看(cclink -ie Communication manual)

说明：  脉冲压缩的匹配滤波。目标距离分别为10米，30米和100米，对于未压缩的脉冲，三个回波信号混叠在一起，不能分辨，而经过脉冲压缩的脉冲信号则可通过匹配滤波收到3个回波信号(Matched filtering for pulse compression.Target distances are 10 metres, 30 metres and 100 metres, respectively. For uncompressed pulses,The three echo signals are overlapped and can not be distinguished. While pulse compression can distinguish three echo signals after matched filtering)

说明：  十大算法程序及论文，数学建模必备，基于Matlab(Ten algorithms and papers, mathematical modeling essential, based on Matlab)

说明：  采用Jakes模型的瑞利信道仿真matlab程序(Rayleigh Channel Simulation matlab Program Using Jakes Model)
