Abstract :
This paper describes the architecture of integrated circuits for base-band processing in 3rd Generation (3G) mobile wireless systems. Wideband CDMA receiver functions including the RAKE, rate de/matching, channel de/interleaving, channel de/coding and multi-user detection are described. Silicon implementations of a 3GPP channel decoder and also a multi-user base-band signal processor are presented. The high speed downlink packet access (HSDPA) system providing downlink data rates in excess of 10 Mbps and the 20 Mbps multiple input/multiple output (MIMO) extensions are also described. The architecture of a 21.6 Mbps MIMO HSDPA receiver for mobile terminals with 2 or 4 antennas is shown that uses the V-BLAST MIMO detection algorithm.
