Diversity multiplexing trade-off for opportunistic multiple access relay channel
This work studies the multiple access relay channel (MARC), specifically it explores the effect of multiuser diversity on the diversity multiplexing trade-off (DMT) performance of the MARC. A new opportunistic channel access communication scheme is proposed where the user selection depends only on the source-destination channels coefficients. This is proven to be DMT optimal. Both non-orthogonal and orthogonal relay transmission are studied under various cooperation protocols. This work does not assume CSI at the transmitters and assumes only 1-bit feedback from the destination to the sources.
