Performance Analysis of Beam-Switching using One-Dimensional Antenna Arrays

Abstract

Adaptive beamforming (BF) is a well known application of active BF but comes with the cost of high complexity and computational effort in terms of angle and channel estimation. In order to find a low complexity alternative of adaptive BF we investigate the performance of a beam-switching method considering a uniform linear antenna array (ULA), one dimensional BF and two-wave with diffuse power (TWDP) fading. Therefore we compare adaptive BF with analog BF considered as beamswitching using horizontally and vertically arranged ULAs in terms of signal-to-noise ratio (SNR) and achievable rate by means of Monte Carlo simulations.
