| 摘 要： | 对CDMA2000无线网络中的MPEG-4视频传输进行了跨层性能评估，研究无线信道误码引起丢包的情况下MPEG-4视频编码参数对经信道传输后解码得到的图像质量的影响。以3GPP2的CDMA2000网络仿真器为基础搭建了软件仿真系统，对不同无线信道模型以及不同丢帧率条件下MPEG-4编码参数对视频数据传输的影响进行分析和比较，为跨层优化提供有价值的参考。

| Abstract: | This paper presents the cross-layer performance evaluation of MPEG-4 over CDMA2000 wineless network, which focus on influence of MPEG-4 encoding parameters upon quality of decoded video after transmitted through packet-loss channel. The software simulation system is built with the CMDA2000 wireless network simulator of 3GPP2, multiple channel models with different FER are analyzed. The study provides valuable information for cross-layer optimization. |
