Non-Integer Array Based Antenna Deployment for Spectral Efficient Cellular Networks

Antenna arrays are critical in enhancing communication reliability and spectral efficiency within cellular networks. Traditional integer-based designs, while simple and robust, impose limitations on performance scalability. This study explores the underutilized potential of non-integer array configurations for base station deployments. By introducing a novel theoretical framework supported by mathematical derivations and two foundational lemmas, this work demonstrates the superior spectral efficiency and sum-rate capacity achievable with non-integer arrays. Comprehensive MATLAB simulations validate these theoretical predictions across various configurations, fading conditions, and multiuser scenarios. Key findings highlight the consistent performance gains of non-integer arrays over integer-based designs, including improved capacity even under constrained antenna subsets and varying interference conditions. This research paves the way for innovative antenna designs that address the growing demands of next-generation wireless networks, offering practical insights for implementation in high-capacity communication systems.
