NOMA Assisted Downlink Power Allocation in Pinching Antenna Systems Using Convolutional Neural Network
Saeed Mohammadzadeh, Kanapathippillai Cumanan, Zhiguo Ding
In this paper, we consider a flexible-antenna architecture, referred to as a pinching-antenna (PA) system, in which multiple PAs realized by activating small dielectric particles a…
Covariance Matrix Construction with Preprocessing-Based Spatial Sampling for Robust Adaptive Beamforming
Saeed Mohammadzadeh, Rodrigo C. de Lamare, Yuriy Zakharov
This work proposes an efficient, robust adaptive beamforming technique to deal with steering vector (SV) estimation mismatches and data covariance matrix reconstruction problems. I…
Study of AP Association and Users and Power Allocation for Cell-Free Massive MIMO Systems
S. Mohammadzadeh, S. Mashdour, R. C. de Lamare +2
This paper introduces an access point-user (AP-UE) association strategy combined with pilot power allocation to mitigate multiuser interference and enhance spectral efficiency (SE)…
Efficient Robust Adaptive Beamforming Based on Spatial Sampling with Virtual Sensors
S. Mohammedzadeh, R. de Lamare
Robust adaptive beamforming (RAB) based on interference-plus-noise covariance (IPNC) matrix reconstruction can experience serious performance degradation in the presence of look di…
Pilot and Data Power Control for Uplink Cell-free massive MIMO
Saeed Mohammadzadeh, Mostafa Rahmani, Kanapathippillai Cumanan +2
This paper introduces a novel iterative algorithm for optimizing pilot and data power control (PC) in cell-free massive multiple-input multiple-output (CF-mMIMO) systems, aiming to…
