Packet-by-Packet Adaptive Scheme for Video Coding and Transmission Over Wireless IP Networks Using Rate-Compatible Punctured Turbo (RCPT) Codes

Abstract: In this paper, we consider real-time video coding and transmission over packet-switched wireless IP networks, such as WLAN, using RCPT codes and joint source-channel coding (JSCC) with concentration on a packet-by-packet adaptive scheme. We present a systematic design methodology to enable the applicability of JSCC techniques. The performance of H.263+ video coding and transmission over wireless channel modeled as slow Rician fading channels using this approach is studied. Results indicate that a packet-bypack… Show more

“…In [15], the authors describe a packet-by-packet adaptive RCPT-JSCC (Rate-Compatible Punctured Turbo -Joint Source Channel Coding) approach to be used in conjunction with packetized H.263+ video over wireless IP networks. The results of this research clearly demonstrate that with appropriate RCPT-JSCC, packet video can be delivered over a wireless IP network with acceptable end-to-end quality while exhibiting a more graceful pattern of quality degradation compared to fixed channel coding schemes.…”
