In this study, the authors apply a generalised quantise-and-forward (GQF) relaying scheme for multiple access relay channel (MARC). The authors find achievable rate regions of GQF on MARC for both discrete memoryless case and additive white Gaussian channel. They assume that the relay has no access to channel state information (CSI) of the relay–destination link. Through numerical examples, they show that in the absence of CSI at the relay, the GQF scheme outperforms other relaying schemes. They also show that the outage probability of the individual users is lower than that of classic compress-and-forward scheme.
