Description: 请认真阅读采用MATLAB分析WAV文件。
步骤一：选择一个WAV文件作为分析的对象 。（ding.wav）
步骤三：进行 FFT变换并画频域图形 。
步骤四：进行该声波主要频谱的分析。
步骤五：根据该声音的频谱，反演时域图形 。（有失真）
步骤六：进行付立叶逆变换IFFT并画频域图形 。-Please carefully read the WAV files using MATLAB analysis. Step One: Select a WAV file as the target of analysis. (Ding.wav) Step Three: Transform and painting to FFT frequency domain graphics. Step four: the main frequency spectrum of the acoustic analysis. Step 5: According to the sound spectrum, inversion of time-domain graphics. (With distortion) Step six: to carry out inverse Fourier transform frequency domain IFFT and painted graphics.

Description: OFDM信号的编码译码仿真，英文说明更详细。-This 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.
Note: The both the receiver and transmitter must have a copy of the
input data file, as this is used for calculating the exact number
of data words in the transmission.
The scripts should work as extracted. Just run imagetx.m to generate the
OFDM signal. Then run imagerx.m to decode the signal. The initial settings
transmit a wave file Corrs.wav . The decoded OFDM data ( Out.wav ) can be
compared with the original data by listening to the two wave files.
