Future deep space missions are envisioned to implement the Delay Tolerant Network architecture and to offer very high data rate also towards remote planets to support possible human missions. In this perspective, the need for advanced transmission paradigms and reliability means is needed to ensure the success of such missions. On the one hand, the CCSDS protocol implemented at the application and...
This article presents ITU-T G.722 appendix IV which is a packet loss concealment (PLC) algorithm recently standardized by ITU-T 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...
This paper describes techniques which can be used at the encoder and at the decoder of CELP coders to improve their robustness to frame erasures. The techniques address specific problems in different speech classes, in particular stationary voiced and voiced onsets.
