Gaussian-Elimination-Free BP-OSD Algorithm for Short 5G LDPC Codes

In this paper, we propose a two-stage belief-propagation ordered statistics decoding (BP-OSD)-like algorithm, hereafter referred to as BP-LCGCD, tailored to 5G low-density parity-check (LDPC) codes. When standard BP decoding fails, a modified BP (mBP) with an iteration limit determined by the code’s girth and a normali...

LDPC Code Design for ISI Channels via Fitted Detector EXIT Analysis

Channels with memory commonly introduce intersymbol interference (ISI), which complicates reliable coded transmission. For such channels, this paper develops a fitted extrinsic-information-transfer (EXIT) framework for LDPC code design with iterative detection and decoding. The soft-input soft-output (SISO) detector is...
