正交频分复用系统中信号的调制与解调，我们用傅里叶反变换和变换来实现(Orthogonal frequency division multiplexing system signal modulation and demodulation, and we use the inverse Fourier transform to achieve transform)

COM技术内幕，com这方面的技术资料，找了很久··希望对大家有所帮助吧··(COM technology insider com, this technical information, looking for a long time we hope to help)

说明：  MFC编程 实现数据绘制成曲线。经兄弟推荐最终决定用两个控件MCSCOMM与TeeChart来完成此任务。MCSCOMM控件时vc自带的串口控件，TeeChart Pro是一个强大的VCL图表组件，支持上百种2D和3D图表风格，并提供40多个数学和统计函数、无限制的轴和22个调色板(MFC programming realizes data plotting into curves. After recommendation by brothers, we finally decided to use two controls, MCSCOMM and TeeChart, to accomplish this task. TeeChart Pro is a powerful VCL graphics component that supports hundreds of 2D and 3D graphics styles and provides more than 40 mathematical and statistical functions, unlimited axes and 22 palettes.)

生成数字调制类型信号的matlab程序，包括BPSK，QPSK，2FSK,4FSK,QAM等多种类型信号的调制方法(matlab program for digital modelated signal genaration,including BPSK，QPSK，2FSK,4FSK,QAM,etc.)

说明：  OFDM系统仿真 ----比较OFDM系统的IDFT/DFT实现与模拟调制实现仿真代码，其中假设OFDM系统包含8个子载波，fc=1 Hz，子载波频率间隔为1 Hz，每个子载波采用4-QAM调制，符号周期为1秒(OFDM IDFT/DFT 4-QAM FFT/IFFT)

逆变器主程序 和通讯程序 、中断程序、算法及主要编程代码 希望能够帮助大家(The main program and communication program, interrupt program, algorithm, and main programming code of the inverter are expected to help you)

基于宽带OFDM信号的DOA估计，采用经典的CSM算法，聚焦后采用传统MUSIC算法，最后通过谱峰搜素算法得到估计的来波角(Based on broadband OFDM signal DOA estimation, using the classical CSM algorithm, after focusing the traditional MUSIC algorithm, and finally through hormone peak search algorithm to estimate the wave angle)

vc++串口通信 ，可以实现两个串口之间发送字符串(vc++ serial communication between two serial ports that can send a string)
