Iterative Decoding of Product Code
Product codes based on binary block codes are considered. The aim is to use simple block codes as component codes in the constructions. Then, by using interleaving, large codes can be obtained. The fundamental aim of the interleaving is to obtain codes with a structure that is suitable for iterative decoding. We present interleaving strategies for iterative (turbo) decoding of block codes. A si...
متن کاملSearch Based Weighted Multi-Bit Flipping Algorithm for High-Performance Low-Complexity Decoding of LDPC Codes
In this paper, two new hybrid algorithms are proposed for decoding Low Density Parity Check (LDPC) codes. Original version of the proposed algorithms named Search Based Weighted Multi Bit Flipping (SWMBF). The main idea of these algorithms is flipping variable multi bits in each iteration, change in which leads to the syndrome vector with least hamming weight. To achieve this, the proposed algo...

متن کاملIterative Decoding for Bit-Patterned Media Recording Channels with Insertion/Deletion Errors
In bit-patterned media recording (BPMR) systems, the degraded system performance is often caused not only by the intertrack interference (ITI) and the intersymbol interference (ISI), but also by insertion/deletion errors. This insertion/deletion error is one of the major problems in BPMR systems. Therefore, we propose an iterative decoding scheme for a BPMR system to combat the insertion/deleti...
متن کاملExtended bit-filling and LDPC code design
Recently, we [1] proposed a simple-to-implement heuristic, namely, BIT-FILLING, for constructing high rate and high girth LDPC codes. In the present work, we extend BIT-FILLING, and demonstrate that the extended algorithm produces better codes, that is, codes with higher rate/girth and good bit error rate performance. We demonstrate the positive effect of girth on bit error rate performance.
