Abstract

In order to perform coherent demodulation under fading channel conditions, channel phase and amplitude estimation are required at the receiver. 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 in both CPICH (common pilot channel) and DPCCH (dedicated physical control channel). Considering the different link quality between CPICH and DPCCH according to the location of a mobile station (MS), estimation schemes that use both channels are suggested and their performances are compared
