Abstract :
A 0.35/spl mu/m CMOS analog decoder for a 4-state, rate 1/3, block length 16 turbo code operates at 13.3Mb/s and latency of 1.2/spl mu/s and consumes 13.9nJ per decoded bit with a 3.3V supply. The 1.42mm/sup 2/ core IC implements two logarithmic domain MAP decoders and a fully programmable analog interleaver that is configured at power-up.
