摘要：
Forward error control (FEC) and multiple description coding (MDC) are two classical techniques to resist packet loss for Voice over IP (VoIP). AMR-WB codec has been standardized for wideband speech conversational applications and has widely potential applications in the migration of wireless or wired networks toward a single converged IP network. However, how to choose the optimal FEC or MDC for AMR-WB in different loss rate conditions is an unexplored option. In this paper, we compare the performance of different FEC and MDC techniques for AMR-WB codec both analytically and experimentally. Based on the comparison results, some practical configurations of FEC and MDC for AMR-WB codec are obtained.
