Abstract

Spectrally efficient backhaul networks are one of the key-factors for the deployment of next generation wireless cellular systems. The ambitious capacity requirements for future broadband wireless networks and the high infrastructure costs for new cell sites pose new challenges in the design of high capacity point-to-point (PtP) wireless microwave links. In this paper we present a study on PtP links that utilize a peculiar form of multiple-input multiple-output configuration, in which a capacity doubling is obtained by exploiting the geometric characteristics of the Line-of-Sight link. The impact of adaptivity on the maximum achievable transmission distance in presence of the main electronic impairments, for typical physical parameters, is discussed in order to reveal the feasibility and the advantages of this class of solutions.
