使用FFT算法求两个信号的时频二维（互模糊）函数 fft_ambig

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

现代控制理论的全维观测器，用于入门simulink不熟悉的同学入门理解现代控制理论(modern control)

说明：  频分复用信号的生成以及演示，与英文工具书匹配，很好用！(FDM signal generation)

常用数字调制技术，包括BPSK，OQPSK，QPSK，MSK，GMSK，QAM等的调制解调仿真程序，并且包含AWGN及衰落信道下的仿真，对学习数字调制技术有较大帮助(Commonly used digital modulation techniques, including BPSK, OQPSK, QPSK, MSK, GMSK, QAM modulation and demodulation simulation program such and includes AWGN and fading channel simulation, the study of digital modulation techniques of great help)

说明：  可见光通信经典的dco ofdm 和aco ofdm，加高斯白噪声信道，可以使用的。(The classic DCO OFDM and ACO OFDM in visible light communication, with Gaussian white noise channel, can be used.)

三种模拟调制与解调的算法，三种模拟调制为：AM，FM，SSB(Three types of analog modulation and demodulation algorithms, three types of analog modulation for: AM, FM, SSB)

ofdm的采用的改进pts，即m序列pts方法来降低papr(Improvement of the adoption of OFDM pts, namely m sequence pts methods to reduce the PAPR)

说明：  适用于VS2010以后的版本对串口进行读取数据和写入数据到串口。(Applicable to VS2010 and later versions to read data and write data to the serial port.)

适用于VS2010以后的版本对串口进行读取数据和写入数据到串口。(Applicable to VS2010 and later versions to read data and write data to the serial port.)
