A decoding system including a low density parity check (LDPC) processing module and a termination module. The LDPC processing module is configured to receive a test codeword based on a codeword received over a communications channel, and perform, for each row of a parity check matrix, a proce...
A method for controlling an elementary parity node of a decoder for decoding non-binary LDPC codes or a code decoder using at least one non-binary parity constraint, and to the corresponding elementary parity node. The elementary parity ... E Boutillon,L Conde-Canencia 被引量: 0发表: 2014...

A symbol-level iterative decoding scheme of non-binary LDPC coded orthogonal modulation with non-coherent demodulation is presented. Compared to the conventionally used bit interleaved coded modulation with iterative decoding (BICM-ID), the proposed scheme directly combine LDPC codes over GF(q) (q>;...
Emerging standards for wireless communications in the 60GHz band, such as WiGig, IEEE 802.11ad, and IEEE 802.15.3c, require throughputs between 1.5 and 6 Gb/s and use rate adaptive Nonbinary Low Density Parity Check (NB-LDPC) codes as the main form of forward error correction. State-of...
