Low density parity check code (LDPC) has constructed a flexible, low decoding complexity and performance close to Shannon limit benefits. This paper introduces the LDPC codes and bit-interleaved coded modulation with iterative decoding (BICM-ID) scheme, given its log-likelihood ratio belief propagation (LLR-BP) decoding algorithm. Achieved with LDPC codes as component codes in BICM-ID scheme is applied...
This paper presents a scalable and low power low-density parity-check (LDPC) decoder design for the next generation wireless handset SoC. The methodology is based on high level synthesis: PICO (program-in chip-out) tool was used to produce efficient RTL directly from a sequential un-timed C algorithm. We propose two parallel LDPC decoder architectures: (1) per-layer decoding architecture with scalable...
We propose a modified algorithm for decoding of linear codes with low-density generator matrix (LDGM codes) over finite-state binary Markov channels. Simulation results show that the proposed scheme outperforms regular LDPC codes and achieves a performance close to that of turbo codes with much less encoding/decoding complexity
