Claim:
1. A multimode rake receiver, comprising 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; a common signal processing path, at least arranged to process in said first mode said first CDMA radio channel and in said second mode said second CDMA radio channel, wherein said common signal path comprises: a control unit to communicate with the common descrambling and de-spreading unit, and with the common hybrid code generating unit, the control unit to provide a first control signal to the common descrambling and de-spreading unit and to the common hybrid code generating unit, the first control signal to cause the common descrambling and de-spreading unit and the common hybrid code generating unit to be in the first mode, and to provide a second control signal to the common descrambling and de-spreading unit and to the common hybrid code generating unit, the second control signal to cause the common descrambling and de-spreading unit and the common hybrid code generating unit to be in the second mode, the common descrambling and de-spreading unit to operate in only one of the first mode or the second mode at any given point of time depending on whether the first control signal or the second control signal is received.
