In this paper we introduce the concept of degree-profile matching interleavers (DPM-interleavers) and propose an LDPC-coded modulation scheme with a DPM-interleaver for 2<sup>m</sup>-PAM. One advantage of our scheme over conventional LDPC-coded modulation schemes is to support various modulation orders in a single coder/decoder by properly choosing(More)
In this paper, a novel data link layer protocol adopted in the ATSC 3.0 terrestrial broadcast standard is described. The data link layer is a protocol layer between the physical layer and the network layer. The data link layer transports data from the network layer to the physical layer at the sending side and transports data from the physical layer to the(More)
Gallager's decoding algorithm A (GDA) for low density parity check (LDPC) codes is of interest mainly due to its good performance with extremely low complexity. In this paper, we analyze GDA over 2<sup>m</sup>-ary pulse-amplitude modulation (2<sup>m</sup>-PAM). Firstly, we represent its average error probability by means of a recursion formula. We then(More)
