Abstract

Cell sectorization is used extensively to increase the capacity of cellular systems; however, intersector interference caused by nonideal sector antennas limits full realization of sectorization benefits, In this paper, we propose a new technique for sector beam synthesis using phased antenna arrays. We adopt the criterion of minimizing intersector interference, subject to a peak-to-peak ripple constraint on the in-sector power pattern, Spectralfactorization permits a reparameterization yielding an easily solved fractional linear program. The proposed procedure accommodates nonisotropic antenna elements, arbitrary element spacing, and arbitrary sector boundaries, but is limited to uniformly spaced linear arrays. To demonstrate the utilityof the proposed method, it is used to predict antenna array size requirements for a direct-sequence code-division multiple-access (DS-CDMA) cellular system.
