Design of LDPC codes for the unequal power two-user Gaussian Multiple Access ChannelDesign of LDPC codes for the unequal power two-user Gaussian Multiple Access Channel Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2019-05-312018enIn this letter, we describe an LDPC code design framework for the unequal power two-user Gaussian multiple access channel using EXIT charts. We show that the sum-rate of the LDPC codes designed using our approach can get close to the maximal sum-rate of the two-user Gaussian multiple access channel. Moreover, we provide numerical simulation results that demonstrate the excellent finite-length performance of the designed LDPC codes.http://creativecommons.org/licenses/by/4.0/IEEE Wireless Communications Letters75868-871 Balatsoukas-Stimming, Alexios 1986- Liavas Athanasios Λιαβας Αθανασιος Institute of Electrical and Electronics Engineers Channel coding Multiuser channels Wireless communication Communication channels (information theory) Binary phase shift keying Decoding
