In this paper, we consider IOTA-OFDM/OQAM system that improves the transmission power and rate efficiency of conventional OFDM system and propose DF relaying cooperative communication scheme based on the IOTA-OFDM/OQAM system. In the proposed scheme, the destination receives orthogonal signals from source and relay simultaneously and combines using MRC. We demonstrated that the proposed schemes get better BER performance than conventional system because of the diversity gain.
