TD-SCDMA系统BS与UE间频偏的估算方法研究

Study on Estimation Method of Frequency Deviation between BS and UE in TD-SCDMA System

TD—SCDMA系统中BS和UE间的频偏可以根据UE所处的状态选择估算方法,本文研究一种用于连接模式下估算基站与UE频偏的方法,该方法不仅能够比较精确地估计频偏,而且能够消除同频邻小区对频偏估计的影响。

The Methods of frequency deviation estimation between BS（Base Station） and UE（User Equipment） in TD-SCDMA system can be decided by UE states. This paper presents an estimation method of frequency deviation between BS and UE in connecting condition, this method makes frequency deviation estimation more exactly, but also counteracts interference from intra-frequency neighbor cell.
