MULTIMODE RAKE RECEIVER, CELLULAR BASE STATION AND CELLULAR COMMUNICATION DEVICE

摘要

A multimode rake receiver comprise a common antenna interface, arranged to at least receive in a first mode a first CDMA radio channel carrying information encoded according to a first baseband modulation standard and to receive in a second mode a second CDMA radio channel carrying information encoded according to a second baseband modulation standard; and a common signal processing path, at least arranged to process in the first mode the first CDMA radio channel and in the second mode the second CDMA radio channel, wherein the common signal path comprises a common descrambling and de-spreading unit and a common hybrid code generating unit arranged to provide to the common descrambling and de-spreading unit chip codes applicable in the first mode to the first CDMA radio channel and in the second mode to the second CDMA radio channel.
