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...

Free-Ride BCH Codes for Fine-Grained Rate Adaptation: Construction, Decoding, and Analysis

In this paper, we propose free-ride BCH (FR-BCH) codes to enable fine-grained rate adaptation on conventional BCH codes. At the transmitter, a small number of extra bits are superimposed onto the BCH codeword via random or structured superpositions. At the receiver, all candidate extra-bit patterns are enumerated by a...
