Correlated FEC Scheme for Transmission Reliability over Burst Error Wireless Channels

Abstract

This paper presents a novel and efficient error correction scheme with high recovery capability, especially for burst error wireless channels. The proposed scheme introduces a correlated FEC approach that not only increases the FEC recovery capability within its own block, but also in preceding block(s). It uses special algorithm that generates specially correlated coded FEC. This correlated code, when combined with other FEC codes in different block(s), enables the receiver to recover large errors, especially suitable for the recovery of burst losses. This approach is more efficient as it has higher recovery probability than a traditional one with similar amount of redundancy. The ability to substantially improve the recovery probability also enhances system reliability, when integrated with adaptive mechanism.
