With the advent of technology over the recent years, the low-density parity-check (LDPC) codes, which were once seen as an impractical concept, are now poised to be the next big thing in the communication standards of today for their near-capacity performances. Nonetheless, the physical implementation of LDPC decoders is more often than not encumbered by the arithmetic of its decoding algorithm. Entangled...
Driven by its renowned near-capacity performance over a wide spectrum of channels, the capitalization of quasi-cyclic low-density parity-check (QC-LDPC) codes is irrefutably the focal point of research and solution to virtually all communication systems of the next generation. Steered towards non-volatile memory (NVM) storage applications, we introduce a modernistic approach to LDPC decoding in this...
The scrutiny of the class of Reed-Solomon (RS) based quasi-cyclic (QC) low-density parity-check (LDPC) codes has inspired the authors to propose a memory efficient mirror-paradigm (MP) RS-based QC-LDPC code by exploiting the geometrical properties from the RS-based QC-LDPC nomenclature. Without any loss in performance, the proposed MPRS-based QC-LDPC code delivers discernible memory savings that address...
Due to the growing interest in video delivery over unreliable channels, the problem of error concealment in video communication is increasingly important. Our goal is to enable the correct decoding of bitstream, on the top of that, have a maximum playable frame rate and video quality. To be able to better combat packet loss, this article proposes a UEP solution in data partitioned H.264 video. Using...
