Abstract
In this paper, we consider a case where two distributed MIMO systems share the same spectrum. Each of them has to dynamically detect the spectrum of the other. The system model is established and the joint spectrum sensing scheme is studied. The optimal weighting factors are derived. Closed-form expressions of the probability of false alarm and sensing are provided. Simulation results show that the proposed joint sensing scheme can achieve much better sensing performance than that of the single-sensor scheme.
