WCDMA系统中下行链路业务复用处理流程较为复杂。本文通过深入研究 3GPP协议中下行链路业务复用各个处理步骤 ,提出了每个处理步骤的DSP快速实现方案 ,从而得到了用DSP芯片实现下行链路业务复用时的快速处理方案。基于该方案实现的下行链路业务复用具有较小的处理延时。由于上行链路业务复用处理流程相对于下行链路业务复用来说 ,较为简单 ,所以本文提出的各个处理步骤的快速实现方案也可应用于上行链路业务复用处理 ,还可应用于上、下行链路的解业务复用处理
Downlink traffic in WCDMA system multiplexing process is more complicated. In this paper, through deep research on the various processing steps of downlink service multiplexing in the 3GPP protocol, a rapid implementation scheme of DSP for each processing step is proposed, and a fast processing scheme for implementing downlink service multiplexing with the DSP chip is obtained. Downlink traffic multiplexing based on this scheme has a smaller processing delay. Because the uplink service multiplexing process is simpler than the downlink service multiplexing, the rapid implementation solution of each processing step proposed in this document can also be applied to the uplink service multiplexing process, and can also be applied to On the downlink solution to the business of multiplexing
