- W2888189239 abstract "During the last decade, spectrum sharing between different wireless technologies has been suggested as a promising solution to the spectrum scarcity problem. However, with the increasing growth of mobile devices and data rate hungry applications, it becomes a necessity to find more innovative spectrum sharing solutions. This paper proposes a novel three-phases non-orthogonal multiple access (NOMA)-based spectrum sharing strategy between multi-user MIMO (MU-MIMO) communication (comm) systems and collocated MIMO radars. The proposed strategy exploits a win–win relationship between the MIMO radar and MIMO comm systems. The MIMO radar wins the improvement of its performance in terms of probability of detection through the delegation of its transmission to the base-station (BS) that has better channels with the targets. On the other hand, the comm system improves its sum-rate throughput and outage performance through sharing the spectrum originally assigned to the radar. The proposed cooperative spectrum sharing strategy is examined in terms of sum-rate throughput and outage probability for the comm system, and the probability of detection for the MIMO radar. Simulation results are presented to illustrate that the proposed spectrum sharing strategy outperforms the state-of-the-art approaches to spectrum sharing between the MIMO radar and MIMO comm systems." @default.
