Abstract

In this paper the computer implementation of the OFDM modulator and demodulator has been described. The main goal was to create the educational model of OFDM receiver working in acoustic band. The OFDM modulator and demodulator general structure has been discussed and original design has been proposed. The most important parts of the design are symbol synchronization algorithm and QMI / QDD modules adapting raw OFDM signal to the bandlimited channel.
