This code was used for making the practical
measurements in section 2.3 of my thesis. This Matlab code allows an OFDM
signal to be generated based on an input data file. The data can be random
data, a grey scale image, a wave file, or any type of file. The generated
OFDM signal is stored as a windows wave file, allowing it to be viewed,
listened to and manipulated in other programs. The modified wave file can
then be decoded by the receiver software to extract the original data.
This code was developed for the experiments that I performed in my honours
thesis, and thus has not been fully debugged.
This is the original code developed for
the thesis and so has several problems with it. The BER performance given
by the simulations is infact Symbol Error Rate.

This code was used for generating the
performance graphs shown in my thesis. I have updated it to run on Matlab
5.3, however it should still run on Matlab 4. The OFDM simulations are
each in a different directory. The cdma code uses generalised code that
allows for various different tests. The BER performance given by the simulations
is infact Symbol Error Rate.
