Performance Analysis and Comparison of Channel Estimation Algorithms for Downlink in WCDMA Systems
Quan Jing-cai · Electronics Quality · 2002
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. In this paper, Performance analysis and comparison of the channel estimation methods based on CPICH and time multiplexed pilot symbols respectively are made from the computer simulation results.
