Abstract

This research paper presents the development and optimization of a Smart Antenna system for advanced communications using the Signum Data Least Mean Squares (LMS) beamformer with Signum Double application. The mathematical model begins with defining the problem statement and system architecture, followed by a detailed signal model considering received signals, noise, and interference sources. Exploiting the LMS algorithm, the mathematical model describes the iterative weight adjustment process of the antenna array to optimize signal reception. Furthermore, to enhance system performance, the Kaiser Bessel window is applied to reduce peak side lobes, thereby improving the overall antenna array response. The effectiveness of the proposed approach SSDLMS-KW is evaluated through simulations under various communication scenarios, considering metrics such as signal-to-interference-plus-noise ratio (SINR). Results demonstrate the efficacy of the Smart Antenna system in achieving superior communication performance, making it a promising solution for next-generation wireless communication networks.
