Unveiling the potential of fluid antenna multiple access for 6G: A performance study

Abstract

Wireless communication networks advancing towards 6G require new technologies to meet increasing data rate and connectivity demands. Fluid Antenna Multiple Access (FAMA) is a promising technique that can meet these demands by dynamically changing antenna positions. This study presents a comprehensive performance analysis of FAMA technology for 6G networks. Two fundamental FAMA techniques, slow FAMA (s-FAMA) and fast FAMA (f-FAMA), are examined, and mathematical expressions defining key performance metrics for these systems are derived. Rayleigh channel fading model is considered. The numerical results obtained comparatively demonstrate the performance of the two techniques under different scenarios. Consequently, this analysis demonstrates the potential of FAMA in 6G networks and the conditions under which different FAMA types are more advantageous.
