同步MIMO-OFDM系统,分为SNR=10和SNR=20两种参数进行仿真。MATLAB程序。(Synchronous MIMO-OFDM system, into SNR = 10 SNR = 20 and two kinds of parameters for simulation. MATLAB.)

双音频信号处理，模拟电话的各个按键的波形发生情况(Dual audio signal processing, waveform of each key of the occurrence of an analog telephone)

Modulation test for OFDM : This is a set of five (5) codes about COFDM (Coded Orthogonal Frequency Division Multiplexing) and coding schemes such as Convolutional, BCH, Reed Solomon (RS) and Low Density Parity Check (LDPC). The study uses an OFDM signal over an AWGN Channel with white Gaussian noise model, and calculate the Bit Error Rate wich is plotted.
