Abstract

In this paper, software tools which simulate the error correcting capability of forward error correction (FEC) codes, for the transmission of MPEG advanced audio coding (AAC) bitstreams over a wireless channel, are described. The tools consist of two applications. The first application is a channel transmission simulator with the features to set the choice of FEC codes, wireless channel characteristics and observe the simulation results. The second application is a graph plotting software that facilitates analysis of simulation results. Such a tool makes it convenient to investigate the transmission of audio data over wireless links.
