Resilient Signal Reflection under CSI Perturbations: A Robust Approach for Secure RIS Communication
Mahdi Shamsi, Hadi Zayyani, Farokh Marvasti
Reconfigurable Intelligent Surfaces (RIS) have emerged as a transformative technology in wireless communication, enabling dynamic control over signal propagation. This paper tackle…
Augmenting SEFDM Performance in High-Doppler Channels
Mahdi Shamsi, Farokh Marvasti
This paper presents an innovative approach leveraging Spectrally Efficient Frequency Division Multiplexing (SEFDM) with enhancements, including Frequency Domain Cyclic Prefix (FDCP…
A Fast Iterative Method for Removing Impulsive Noise from Sparse Signals
Sahar Sadrizadeh, Nematollah Zarmehi, Ehsan Asadi +2
In this paper, we propose a new method to reconstruct a signal corrupted by noise where both signal and noise are sparse but in different domains. The problem investigated in this…
NLOS Mitigation Using Sparsity Feature And Iterative Methods
Abbas Abolfathi, Fereidoon Behnia, Farokh Marvasti
Well-known methods are employed to localize mobile station (MS) using line of sight (LOS) measurements. These methods may result in large error if they are fed with non LOS (NLOS)…
Bounds on Discrete Fourier Transform of Random Mask
Nematollah Zarmehi, Farokh Marvasti
This paper proposes some bounds on the maximum of magnitude of a random mask in Fourier domain. The random mask is used in random sampling scheme. Having a bound on the maximum val…
