Error correction capabilities of BCH codes with interleaving in Rayleigh fading channel

Error correction capabilities of several BCH codes with different code lengths are investigated for a Rayleigh fading channel where burst bit errors occur frequently. The decoded BERs are compared under the same delay time condition for bit interleaving. Error sequences obtained from laboratory experiment are used for GMSK BER calculations. The results show that difference in the effects of code lengths on error correction capabilities is almost negligible under the slow fading with short delay time (short interleaving size) conditions
