随着移动通信和多媒体通信的飞速发展,构建于无线网络之上的多媒体服务已经被越来越多的用户所接受。2.5代移动通信CDMA的典型带宽为30～50kb/s,可以传输低速的视频,但是对多媒体应用来说,其质量还是未能达到要求。在现有技术条件下,如何在CDMA无线信道中保证视频流的质量以及如何扩大带宽提高视频质量,是值得研究的问题。文中提出了一种在多个CDMA通道中进行视频传输的框架,利用多个CDMA无线信道绑定的方法,提高了视频的帧率和分辨率。
With the rapid development of mobile communication and multimedia communication, multimedia services built on the wireless network have been accepted by more and more users. 2.5 on behalf of mobile communication CDMA typical bandwidth of 30 ~ 50kb / s, can transmit low-speed video, but for multimedia applications, its quality or failed to meet the requirements. Under the condition of the prior art, how to ensure the quality of the video stream in the CDMA wireless channel and how to increase the bandwidth and improve the video quality is a problem worth studying. In this paper, a framework for video transmission over multiple CDMA channels is proposed, which improves the video frame rate and resolution by using multiple CDMA radio channel bonding methods.
