BLUETOOTH PERFORMANCE IMPROVEMENT OVER DIFFERENT CHANNELS THROUGH CHANNEL CODING

Abstract

It is known that Bluetooth systems employ a Hamming (15, 10) code for error correction. In this paper, we propose different error correction coding schemes for this purpose. A comparison study between the Hamming (7, 4), the cyclic (15, 11) and the BCH (15, 7) codes is held in the paper to choose an alternative to the Hamming (15, 10) code. The simulation experiments are held over both an Additive White Gaussian Noise (AWGN) channel and a Rayleigh fading channel. The experimental results reveal the superiority of the BCH (15, 7) code to all other coding schemes if a large redundancy is accepted. If the issue of redundancy is of major concern, the Hamming (7,4) code is the best.
