Abstract

This paper presents a method of transmitting video over the cdma2000 mobile systems. In this method, the video bit-stream, after splitting, is transmitted via the supplemental channels of the cdma2000 reverse link. The method takes advantage of the direct spread multiplexing structure of the supplemental channels to transmit divided video at differing priority classes. This is accomplished by adopting the relative gain adjustment strategy where the most error sensitive video information is transmitted via a channel with higher power. The most challenging aspect of this investigation has been to maintain full compatibility with the cdma2000 standard. In particular, for the reverse link where the power allocation is tightly controlled, this strategy has been successfully deployed by taking advantage of the flexibility of its link budget. Finally, we will demonstrate that this strategy can result in a significantly higher quality of the reconstructed video data when transmitted over time-varying multipath fading of IMP-2000 channels.
