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.
Note: I have tried this script set in Matlab 5.1 and found that is does not
work correctly. If you have to get it working under matlab 5, send me an email
and I will fix up the errors.
