1. A system for rate matching and de-rate matching, the system comprising: a memory configured to store a plurality of blocks of data; a digital signal processor (DSP) configured to: pre-compute permutation parameters common to the plurality of blocks, wherein the plurality of blocks are subject to a set of given puncturing parameters; receive a set of pre-computed puncturing thresholds; and for one or more blocks in the plurality of blocks compute a block signature from the pre-computed puncturing thresholds; match the block signature to one of a set of pre-computed zone signatures, derive a zone index corresponding to the one pre-computed zone signature, and apply pre-computed permutation and puncturing transformations corresponding to the zone index to the block.
