In this paper, noncoherent differential binary phase shift keying (DPSK) technique which eliminates the need for channel estimation cost is applied to the MARC system model that uses maximum likelihood detection approach at the common destination. Noncoherent DPSK modulation of the MARC system model provides full diversity gain that has been observed at the resulting Monte-Carlo simulation. © 2015 IEEE.tr10.1109/SIU.2015.7129875info:eu-repo/semantics/closedAccessDifferential modulationmultiple access relay channelnetwork codingConference Object523526N/A
