ddc lowpass

说明：  中频30MHZ，带宽5MHZ，脉宽25us，采样率140MSPS(If 30MHz, bandwidth 5MHz, pulse width 25us, sampling rate 140msps)

某智能设备公司开关量采集系统（Modbus RTU），很不错哦！对于该类设备基本上都可以通用，只是“寄存器地址”不一样。我就参照该源程序写了一款SOS应急呼叫系统、酒店客房插卡取电、退房呼叫系统等。保证原创，独一无二。(A smart device switch acquisition system (Modbus RTU), very good, oh! Can be generic, such equipment is basically just not the same register address. I refer to the source Admission card, write a SOS emergency call system, hotel rooms, check out the call system. Guaranteed original, unique.)

说明：  OFDM仿真，包括仿真图，功率谱，星座图等(OFDM simulation, including simulation diagram, power spectrum, constellation diagram, etc.)

虚拟串口工具，可以在普通电脑上虚拟成对串口，方便进行串口编程的本地调试(Virtual Serial Port Tool, which can be virtual paired serial ports on ordinary computers, facilitates the local debugging of serial port programming.)

ofdm的编码过程，用evm和比特率进行对比(The encoding process of OFDM is compared with EVM and bit rate)

说明：  使用pyqt编写的界面程序，实现串口网络通信(The interface program written by pyqt is used to realize the serial port network communication)

说明：  基于music算法的均匀线阵的标量阵与矢量阵的方位估计(DOA estimation of scalar array and vector array based on music algorithm)
