... tackled the problem of optimal design of linear arrays in a cellular systems under the assumption of Gaussian interference. Two design problems are considered:maximization of the ergodic capacity ... power interferingdue to shadowing effects In this section, we investigate the impact of nonequal in- terfering powers caused by shadowing on the optimal an-tenna spacings. This amounts to include ... antenna spacings Δ through nonlinear relation-ships. The first problem we tackle is that of finding the set of optimal spacingsΔ that minimizes the average (with respectto fading) interference...
