| Title: | Protograph-based LDPC-Hadamard codes | Authors: | Zhang, PW Lau, FCM Sham, CW |
Issue Date: | 2020 | Source: | IEEE wireless communications and networking conference. Proceedings, 2020, v. 2020-May, 9120683 | Abstract: | We propose a novel type of ultimate-Shannon-limit-approaching codes, namely protograph-based low-density parity-check Hadamard (PLDPC-Hadamard) codes in this paper. We also propose a systematic way of analyzing such codes using Protograph EXtrinsic Information Transfer (PEXIT) charts. Using the analytical technique we have found a code of rate about 0.05 having a theoretical threshold of -1.42dB. At a BER of 10^{-5}, the gaps of our code to the Shannon capacity for R=0.05 and to the ultimate Shannon limit are 0.25 dB and 0.40 dB, respectively. | Keywords: | PEXIT chart PLDPC-Hadamard code Ultimate Shannon limit |
