Based on analyzing the channel of TD-SCDMA system, It mainly expatiates and analyses the factors that affect TD-SCDMA system link balance, including the function of different parameters, the link of different services, the link between downlink and uplink, the link between TCH and CCCH.
TD-SCDMA系统TDD的工作方式、丰富多彩的业务以及智能天线的应用,使得链路分析更为复杂,需要考虑多个方面的平衡,包括不同业务间、上行与下行、公共信道与业务信道、链路预算各参数间等。
In WCDMA/FDD (Wideband Code Division Multiple Access Frequency Division Duplexing), proposed for the third generation mobile communication systems, downlink channel estimation can be performed by using code multiplexed CPICH (common pilot channel) and time multiplexed pilot symbols.
在WCDMA/FDD第三代移动通信系统中,下行链路的信道估计有基于公共导频信道(CPICH)和基于时分复用导频符号两种方式。
