Abstract

The new networking paradigm of opportunistic spectrum sharing is a promising technology for mitigating the scarcity of spectrum, which has resulted from the exponential increase in the number of wireless devices and ubiquitous services. In light of the new concept of Authorized/Licensed Shared Access (ASA/LSA), in this work, we consider the coexistence and spectrum sharing between a collocated multiple-input-multiple-output (MIMO) radar and a full-duplex (FD) multi-user MIMO cellular system consisting of a FD base station (BS) serving multiple downlink and uplink users simultaneously, and accordingly focus on maximizing the detection probability of the radar. The main objective of this paper is to develop an optimization technique for jointly optimizing the beamforming weights at the BS and transmit power for uplink users that can maximize the detection probability of radar while guaranteeing the quality-of-service requirements of each user and power budget for the uplink users and the BS. The joint beamforming design is a non-convex problem which, we convert into a second-order cone programming (SOCP) problem and propose an iterative algorithm for finding the optimal solution. Numerical results demonstrate the feasibility of the spectral coexistence and show a scalable trade-off in performance of both systems.
