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...
