Abstract :
A programmable turbo decoder is designed for multiple 3G wireless standards, which mainly consists of a configurable SISO decoder and a 16 b SIMD processor equipped with 5 processing elements and custom instructions for incremental block interleavers. The decoder occupies 8.90 mm/sup 2/ in 0.25 /spl mu/m CMOS with 5 metal layers, and exhibits a maximum decoding rate of 5.48 Mb/s.
