摘要:
Provided are devices, systems and methods for rate matching and de-rate matching on digital signal processors. In one embodiment, a device for rate matching and de-rate matching, includes an interface for receiving a plurality of blocks of data and digital signal processor 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 and receive a set of pre-computed puncturing thresholds. For one or more blocks in the plurality of blocks, the DSP computes a block signature from the pre-computed puncturing thresholds; matches the block signature to one of a set of pre-computed zone signatures, derives a zone index corresponding to the one pre-computed zone signature, and applies pre-computed permutation and puncturing transformations corresponding to the zone index to the block.
