On proportional fairness of uplink spectral efficiency in cell-free massive MIMO systems
Viet Quoc Pham, Ha Hoang Kha, Le Ty Khanh
This paper is concerned with the proportional fairness (PF) of the spectral efficiency (SE) maximization of uplinks in a cell-free (CF) massive multiple-input multiple-output (MIMO…
Deep Learning for Uplink Spectral Efficiency in Cell-Free Massive MIMO Systems
Le Ty Khanh, Pham Quoc Viet, Ha Hoang Kha +1
In this paper, we introduce a Deep Neural Network (DNN) to maximize the Proportional Fairness (PF) of the Spectral Efficiency (SE) of uplinks in Cell-Free (CF) massive Multiple-Inp…
Interference Alignment Designs for Secure Multiuser MIMO Systems: Rank Constrained Rank Minimization Approach
Tung T. Vu, Ha Hoang Kha, Trung Q. Duong
In this paper, we formulate the interference alignment (IA) problem for a multiuser multiple-input multiple-output (MIMO) system in the presence of an eavesdropper as a rank constr…
Particle Swarm Optimization for Weighted Sum Rate Maximization in MIMO Broadcast Channels
Tung T. Vu, Ha Hoang Kha, Trung Q. Duong +1
In this paper, we investigate the downlink multiple-input-multipleoutput (MIMO) broadcast channels in which a base transceiver station (BTS) broadcasts multiple data streams to K M…
Wiretapped Signal Leakage Minimization for Secure Multiuser MIMO Systems via Interference Alignment
Tung T. Vu, Ha Hoang Kha, Trung Q. Duong +1
In this paper, interference alignment (IA) is designed for secure multiuser multiple-input multiple-output systems in the presence of an eavesdropper. The proposed IA technique des…
