Abstract
A 3GPP-compliant 4.1 Mb/s channel decoder supports data and voice calls in a unified Turbo/Viterbi architecture with hardware interleaver memory and pattern computation. The 9 mm/sup 2/ chip in 0.18 /spl mu/m 1.8 V 6LM CMOS operates at 110 MHz and consumes 306 mW when decoding 2 Mb/s data and voice calls.
