Abstract
A plurality of turbo decoder engines store extrinsic values when concurrently decoding a received signal encoded within rows and columns of an interleaving matrix where interleaved values stay in a same re-ordered row during interleaving. An extrinsic reader and extrinsic writer accesses extrinsic memories using extrinsic addresses. A deinterleaver accesses the extrinsic addressable memories by arranging storage of the extrinsic values by the same rows of the same interleaving matrix that was used to encode the received signal, each of the rows corresponding to one of the plurality of turbo decoder engines, and, in embodiments, can group the extrinsic values such that all the extrinsic values in each one of the rows of the interleaving matrix go in a same one of the plurality of the extrinsic addressable memory. The deinterleaver can skip read of extrinsic values corresponding to dummy entries in the interleaving matrix.
