Performance of QUBO-Formulated MIMO Detection Under Hardware Precision Constraints
Seyedkhashayar Hashemi, Elisabetta Valiante, Ignacio Rozada +1
The evolution of multiple-input, multiple-output (MIMO) systems requires the efficient detection algorithms to overcome the exponential computational complexity of optimal maximum…
RIS with Coupled Phase Shift and Amplitude: Capacity Maximization and Configuration Set Selection
Seyedkhashayar Hashemi, Masoud Ardakani, Hai Jiang
A reconfigurable intelligent surface (RIS) is a planar surface that can enhance the quality of communication by providing control over the communication environment. Reflection opt…
Optimal Configuration of Reconfigurable Intelligent Surfaces with Arbitrary Discrete Phase Shifts
Seyedkhashayar Hashemi, Hai Jiang, Masoud Ardakani
We address the reflection optimization problem for a reconfigurable intelligent surface (RIS), where the RIS elements feature a set of non-uniformly spaced discrete phase shifts. T…
