fft_plot
routine to take the Fourier transform of a signal and plot both the time and frequency domain representations. Typical use:
>> n = 100 number of data points
>> dt = 0.01 spacing between samples
>> t = 0:dt:(n-1)*dt time vector
>> y = sin(2*pi*10*t) 10 Hz sin wave
>> fft_plot(y,dt) plot of signal in time and frequency domain

OFDMcode
OFDM系统仿真，包含了发射、信道估计、接受等完整的OFDM系统仿真(his simulation script set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes the WAV to extract the data. settings.m contains all the common settings to specify all the simulation parameters such as FFT size, number of carriers, input data source file, input and output WAV files, etc. See settings.m for more details. )
