Title Proper : OPTIMIZATION OF PERMUTATION KEY FOR -ROTATION LDPC CODE
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : The original low-density parity-check (LDPC) codes were developed by RobertGallager in early 1960 and are based on a random parity-check matrix construction.In the mid 1990بs it was discovered that LDPC codes could be modified slightlyto provide the more powerful error correction. These newer LDPC codes, basedon an irregular column weight in the underlying check matrix, were still definedwith random construction techniques. The گ‍-rotation LDPC codes discovered byEchard are a family of LDPC codes completely defined by a small set of integersand have several symmetrical.
