Abstract:
1. A communication device for a wideband code division multiple access communication (W-CDMA) system, the communication device comprising: an antenna interface, a controller, a front end processor, a packet generator, a packet writer and one or more digital signal processors; wherein the antenna interface is configured to receive one or more antenna signals comprising a superposition of a plurality of reflections of a signal transmitted by one or more UEs, the signal comprising scrambled and spreaded symbols associated with one or more physical channels per UE, and to provide the one or more antenna signals to the front end processor; wherein the controller configured to determine a number of fingers corresponding to the plurality of reflections and to assign a plurality of fingers to a UE in accordance with the number, wherein the front end processor is configured to receive the one or more antenna signals, to calculate soft symbols representing the symbols transmitted by the UE using descrambling and despreading of the one or more antenna signals using the plurality of fingers assigned to the UE, each soft symbol being associated with a respective symbol index, UE identifier, finger index and physical channel identifier, and to provide the soft symbols to the packet generator; wherein the packet generator is configured to receive the soft symbols from the front end processor and to organize the soft symbols into packets, each packet comprising the soft symbols from the plurality of fingers assigned to a respective UE associated with one physical channel of the one of more physical channels and with the same symbol index; wherein the packet writer is configured to write the packets into a system memory; and wherein the one or more digital signal processors is configured to access the packets from the system memory and to process the packets.
