Lens-based Millimeter Wave Reconfigurable Antenna NOMA
Mojtaba Ahmadi Almasi, Roohollah Amiri, Mojtaba Vaezi +1
This paper proposes a new multiple access technique based on the millimeter wave lens-based reconfigurable antenna systems. In particular, to support a large number of groups of us…
Reinforcement Learning for Self-Organization and Power Control of Two-Tier Heterogeneous Networks
Roohollah Amiri, Mojtaba Ahmadi Almasi, Jeffrey G. Andrews +1
Self-organizing networks (SONs) can help manage the severe interference in dense heterogeneous networks (HetNets). Given their need to automatically configure power and other setti…
Impact of Beam Misalignment on Hybrid Beamforming NOMA for mmWave Communications
Mojtaba Ahmadi Almasi, Mojtaba Vaezi, Hani Mehrpouyan
This paper studies hybrid beamforming (HB)-based non-orthogonal multiple access (NOMA) in multiuser millimeter wave (mmWave) communications. HB offers power-efficient and low-compl…
A New Millimeter Wave MIMO System for 5G Networks
Mojtaba Ahmadi Almasi, Roohollah Amiri, Hani Mehrpouyan
Millimeter Wave (mmWave) band provides a large spectrum to meet the high-demand capacity by the 5th generation (5G) wireless networks. However, to fully exploit the available spect…
Non-Orthogonal Multiple Access Based on Hybrid Beamforming for mmWave Systems
Mojtaba Ahmadi Almasi, Hani Mehrpouyan
This paper aims to study the utilization of non-orthogonal multiple access (NOMA) in hybrid beamforming (HB) multi-user systems called HB-NOMA to serve a large number of mobile use…
Reconfigurable Antenna Multiple Access for 5G mmWave Systems
Mojtaba Ahmadi Almasi, Hani Mehrpouyan, David Matolak +2
This paper aims to realize a new multiple access technique based on recently proposed millimeter-wave reconfigurable antenna architectures. To this end, first we show that integrat…
