COMMUNICATION DEVICE FOR WIDEBAND CODE DIVISION MULTIPLE ACCESS COMMUNICATION (W-CDMA) SYSTEM, A METHOD FOR USE THEREIN AND AN ASSOCIATED SEMICONDUCTOR DEVICE

摘要

A communication device (1) for a wideband code division multiple access communication (W-CDMA) system is described. The communication device has an antenna interface (AIF), a front end processor (FE), a packet generator (PG), a packet writer (PW) and one or more digital signal processors (DSP1, DSP2). The front end processor (FE) is configured to receive one or more antenna signals from the antenna interface (AIF) and to calculate soft symbols representing symbols transmitted by a UE (UE0, UE1) using descrambling and despreading of the one or more antenna signals using a plurality of fingers assigned to the UE. The packet generator (PG) is configured 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. The packet writer (PW) is configured to write the packets into a system memory (SYSMEM). The one or more digital signal processors (DSP1, DSP2) are configured to access the packets from the system memory (SYSMEM) and to process the packets.
