Nordstrom-Robinson (NR) code followed by 4 quadrature-amplitude modulation (4QAM) mapping is one of the working modes in the Chinese digital television terrestrial broadcasting (DTTB) standard, where the outer code is a low-density parity-check (LDPC) code. Since LDPC decoders usually accept soft rather than hard inputs for better error performance, soft NR decoders are highly recommended. In this...
Low-density parity-check (LDPC) codes are nowadays one of the hottest topics in coding theory, notably due to their advantages in terms of bit error rate performance and low complexity. In order to exploit the potential of the Wyner-Ziv coding paradigm, practical distributed video coding (DVC) schemes should use powerful error correcting codes with near-capacity performance. In this paper, new ways...
