Abstract: Low density parity check (LDPC) lattices were the first family of lattices equipped with iterative decoding algorithms. We introduce quasi-cyclic LDPC (QC LDPC) lattices as a special case of ...

Kaiserslautern, Germany, Apr. 30 2015 – Creonic GmbH, a leading IP core provider for communications, announced today the release of their new CCSDS LDPC encoder and decoder IP cores for the satellite ...

Abstract: We investigate the use of rate-compatible lowdensity parity-check (RC-LDPC) codes as part of a soft decodeand- forward (SDF) protocol over the half-duplex relay channel. We propose a new ...
