TD-SCDMA中码道激活算法研究

Research on Activated Arithmetic of Code-Division Channel in TD-SCDMA

介绍了TD-SCDMA物理层中有关扩频部分的技术,并针对不同的高层配置,即在不同时隙不同码道的配置下,着重分析上行和下行码道激活的基本原理以及关键技术。

This article introduces firstly the frequency spreading and modulation of TD-SCDMA physical layer, then the basis principle and key technology in code-division channel activation module is discussed in both uplink and downlink with the different timeslot and OVSF branch that is configured by high layer.
