Outage Probability Analysis of MRC-Based Fluid Antenna Systems under Rician Fading
Tummi Ganesh, Soumya P. Dash, Italo Atzeni
This paper investigates a fluid antenna system (FAS) where a single-antenna transmitter communicates with a receiver equipped with a fluid antenna (FA) over Rician fading channels.…
Multi-User Symbol Detection with XL Reception: Dynamic Metasurface Antennas with Low Resolution ADCs
Rahul K. Pal, Soumya P. Dash, Barathram Ramkumar +1
Dynamic Metasurface Antennas (DMAs) have been recently proposed as a cost- and energy-efficient front-end solution for eXtremely Large (XL) antenna array systems, supporting scalab…
Symbol Error Analysis for Fluid Antenna Systems with One- and Two-Dimensional Modulation Schemes
Soumya P. Dash, George C. Alexandropoulos
This paper considers a Fluid Antenna (FA) system comprising a single-antenna transmitter that communicates with a receiver equipped with an FA array with ports. The transmitter…
Compact Reconfigurable Intelligent Surface with Phase-Gradient Coded Beam Steering and Controlled Substrate Loss
