Due to the outstanding characteristics of Low-Density Parity-Check (LDPC) codes such as high decoding performance, high throughput, low complexity, they have been accepted as the standard codes for the 5G NR. In this paper, we propose two LDPC decoding algorithms: Hybrid Offset Min-Sum (HOMS) and Variable Offset Min-Sum (VOMS), which are aimed at improving the error correction performance. The main idea of the HOMS\/VOMS algorithm is to apply modified factors to both variable-nodes and check-nodes updated processing in order to compensate the extrinsic messages overestimation of the MS-based algorithms and increase the protection ability for degree-1 variable-nodes. The simulation results show that at the Bit-Error-Rate (BER) of 10-5, the proposed HOMS\/VOMS algorithm achieves the decoding gain up to 0.2 dB compared to the Offset Min-Sum (OMS) algorithm, with a slight increase in decoding complexity.<\/jats:p>","DOI":"10.12720\/jcm.17.5.358-364","type":"journal-article","created":{"date-parts":[[2022,5,13]],"date-time":"2022-05-13T07:01:39Z","timestamp":1652425299000},"page":"358-364","source":"Crossref","is-referenced-by-count":1,"title":["High-Performance and Low-Complexity Decoding Algorithms for 5G Low-Density Parity-Check Codes"],"prefix":"10.12720","author":[{"name":"Department of Electronics Engineering, Faculty of Electrical and Electronics Engineering.
