发明名称 A METHOD AND APPARATUS FOR QAM DEMODULATION IN A GENERALIZED RAKE RECEIVER
摘要 A wireless communication device includes a Generalized RAKE (G-RAKE) receiver circuit that is configured to determine a traffic-to-pilot gain scaling parameter as part of the impairment correlation determination process that underlies (G-RAKE) combining weight generation In this manner, the receiver circuit conveniently and accurately accounts for gain differences between the pilot channel of a received CDMA signal, as used for channel estimation, and the traffic channel(s) of the CDMA signal, which carry received data to be recovered The gain difference accounting enables proper demodulation of amplitude-modulated traffic signals By way of non-limiting example, such gain scaling may be used for demodulating/decoding High Speed Downlink Packet Access (HSDPA) signals used in Wideband Code Division Multiple Access (W-CDMA) systems.
