Abstract:
1. A method for storing log likelihood ratios (LLR) in an interleaved form in memory to reduce memory requirements comprising: receiving a plurality of interleaved codewords; obtaining at least one LLR for the plurality of interleaved codewords; storing the at least one LLR in a memory that is partitioned into a plurality of nodes, wherein each of said interleaved codewords has associated therewith a unique link list in which at least one of said nodes has been dynamically allocated from a link list of free nodes, and wherein the at least one LLR is stored in the at least one node; deinterleaving the plurality of interleaved codewords after the at least one LLR has been stored in the memory; and performing through a decoder a bit decision of the deinterleaved codewords using the stored at least one LLR.
