摘要

本文研究了基于ip的CDMA蜂窝网络中多媒体传输的跨层适应与优化问题。将资源需求考虑为源编码率和每信息比特能量与噪声比的乘积的总和，提出了一种联合源编码-功率控制(JSCPC)与联合源信道编码(JSCC)相结合的策略，以最大限度地提高传输视频的质量，同时使总资源消耗最小。我们集中研究了RTP/UDP/IP传输协议的使用，并结合了H.264/AVC编码器的网络自适应特性，并证明了所提出的方法可以提高频谱效率和网络利用率。

On cross-layer adaptivity and optimization for multimedia CDMA mobile wireless networks

We study a problem in cross-layer adaptation and optimization for multimedia delivery over IP-based CDMA cellular networks. By considering the resource requirements as the aggregate of the products of source coding rates and the energy per information bit to noise ratio, we propose a joint source coding-power control (JSCPC) strategy combined with joint source-channel coding (JSCC) to simultaneously maximize the quality of the delivered video while minimizing the total resource consumption. We concentrate on the use of the RTP/UDP/IP transport protocol and incorporate the network adaptive features of the H.264/AVC coder and show that the proposed approach can provide both improved spectral efficiency and network utilization.
