We consider a K -user dirty multiple access channel (DMAC) with non-causally known SI at the transmitters, where K users send independent messages to a common receiver with a FA capable of changing its location depending on the channel condition. By connecting Jakes’ model to copula theory through Spearman’s ρ rank correlation coefficient, we accurately describe the spatial correlation between the FA channels, and derive a closed-form expression for the outage probability (OP) under Fisher-Snedecor F fading. Results confirm that a FA-aided receiver can achieve better performance in multiuser communication: ( i ) increasing the number of FA ports as well as FA size can significantly lower the OP; (ii) FA can support a large number of users using only one FA at the common receiver in a few wavelengths of space.}, organization = {Engineering and Physical Sciences Research Council (EPSRC) (Grant Number: EP/W026813/1)}, organization = {MCIN/AEI/10.13039/501100011033 through grants EMERGIA20 00297 and PID2020-118139RB-I00}, organization = {Consejería de Transformación Económica, Industria, Conocimiento y Universidades of Junta de Andalucía}, organization = {Institute of Information and Communication Technology Promotion (IITP)}, organization = {Ministry of Science and ICT (MSIT), Korea (Grant Number: 2021-0-02208 and 2021-0-00486)}, publisher = {IEEE}, keywords = {Copula theory}, keywords = {Fading channels}, keywords = {Performance analysis}, title = {Fluid Antenna-Assisted Dirty Multiple Access Channels Over Composite Fading}, doi = {10.1109/LCOMM.2023.3344296}, author = {Rostami Ghadi, Farshad and López Martínez, Francisco Javier and Wong, Kai Kit and Chan-Byoung Chae and Kin-Fai Tong and Yangyang Zhang}, }
