Title
A low complexity packet loss concealment algorithm for ITU-T G.722
Abstract
This article presents ITU-T G.722 Appendix IV which is a Packet Loss Concealment (PLC) algorithm recently standardized by ITUT for G.722 decoding in the presence of frame erasures. This algorithm is suitable for applications that may encounter frame erasures or packet losses with a special focus on complexity constraints For example, G.722 Appendix IV is very suitable for DECT Next Generation and VoIP using low cost devices. Besides, we also describe some minor algorithmic modifications to G.722 Appendix IV that improve subjective quality. We discuss G.722PLC performance based on formal ITU-T test results as well as additional informal experiments.
