Description/Abstract

Abstract—Near-Capacity Multi-user Network-coding (NCMN)
based systems operating in multiple modes and relying on
an amalgamated Irregular Convolutional Code, a Unity-Rate
Code and M-ary Phase-Shift Keying are proposed. We consider
a multiuser network in which the users cooperatively trans-
mit their independent information to a common base station
(BS). Extrinsic Information Transfer (EXIT) charts were used
for designing the proposed NCMN scheme for the sake of approaching the Discrete-input Continuous-output Memoryless
Channel’s (DCMC) capacity. The NCMN systems are capable of
simultaneously exploiting the advantages of all the new modes we designed for our system and those of the conventional mode. The design principles presented in this contribution can be extended to a vast range of NCMN based systems using arbitrary channel coding schemes.
