Error-resilient H.263 video coding for wideband CDMA systems

Abstract

Multimedia services for third generation communication systems have drawn much attention recently. Rich multimedia applications, such as videoconferencing, telemedicine, and video-on-demand, are proposed and will be implemented in the near future owing to the capability of broadband mobile communications. However, the interference and noise in the wireless channel become major obstacles in the implementation of bit-error-rate sensitive applications. In this paper, a novel error-resilient H.263 video codec, cooperating with smart antenna techniques, is introduced which provides robust wireless video transmission. An end-to-end reverse link wideband CDMA (WCDMA) system simulation is performed using SPW, with performance measured in terms of bit error rates and PSNR.
