OFDM matlab 水声通信程序，带有水声同步头，OFDM调制解调(OFDM matlab acoustic communication program, the first sync with the sound of water, OFDM modulation and demodulation)

this is a paper for pcf beam splitter!

生成2KHz和8KHz的混合信号,使该信号通过上述滤波器,观察滤波前后的波形变化和频谱分布情况, 在改信号中加入高斯白噪声,(The mixed signal of 2KHz and 8KHz is generated so that the signal passes the above filter, the waveform change and spectrum distribution before and after filtering are observed, and Gao Si white noise is added to the modified signal.)

双STM32 主从通讯 主硬件IIc 从采用中断(Two STM32 communication,master use hardware IIc ,slave use interrupt)

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.)

说明：  大气波导下，电磁波射频追踪研究，利用Matlab进行仿真(Radio Frequency Tracking of Electromagnetic Waves in Atmospheric Waveguide)

C++开发104协议，支持主从站。支持多客户端连接(C++ develops 104 protocol to support master and slave stations. Support multi-client connection)

这是正交空时分组码中使用16QAM调制的源程序(16qam for OSTBC )
