Title: Systems and methods for a turbo decoder in a universal mobile telecommunication system (UMTS)

Abstract: According to some embodiments of the invention, a turbo decoder in a Universal Mobile Telecommunication System (UMTS) is provided, the turbo decoder comprising: a plurality of maximum a posteriori (MAP) engines; a first plurality of extrinsic memory banks and a second plurality of extrinsic memory banks; and wherein each of the first and second pluralities of extrinsic memory banks is accessible by at least one of the plurality of MAP engines, and wherein each of the first and second pluralities of extrinsic memory banks is configured to organize data according to a R.times.C matrix having a format similar to that of an interleaver table. During decoding, the first and second pluralities of extrinsic memory banks may be accessed for data by a MAP engine such that the first and second pluralities of extrinsic memory banks function as an interleaver or a de-interleaver of extrinsic information within the turbo decoder.
