Robust and Feasible QoS-Aware mmWave Massive MIMO Hybrid Beamforming
Mohsen Tajallifar, Ahmad R. Sharafat, Halim Yanikomeroglu
Hybrid beamforming (HB) with quality-of-service (QoS) provisioning per stream in millimeter waves is indispensable in 5G/6G networks. HB includes baseband and radio frequency (RF)…
Joint Power Control, Channel Assignment and Cell Association in Heterogeneous Cellular Networks
Shahla Mohsenifard, Ahmad R. Sharafat, Halim Yanikomeroglu
Heterogeneous network (HetNet) is a promising concept for increasing capacity and alleviating spectrum scarcity. In HetNets, however, channel assignment and transmit power control…
E2E Migration Strategies Towards 5G: Long-term Migration Plan and Evolution Roadmap
Abulfazl Zakeri, Narges Gholipoor, Mohsen Tajallifar +4
After freezing the first phase of the fifth generation of wireless networks (5G) standardization, it finally goes live now and the rollout of the commercial launch (most in fixed 5…
Resource Allocation for Energy-Efficient Device-to-Device Communication in 4G Networks
Sajjad Mehri Alamouti, Ahmad R. Sharafat
Device-to-device (D2D) communications as an underlay of a LTE-A (4G) network can reduce the traffic load as well as power consumption in cellular networks by way of utilizing peer-…
Robust Stackelberg game in communication systems
saeedeh parsaeefard, Mihaela van der Schaar, Ahmad R. Sharafat
This paper studies multi-user communication systems with two groups of users: leaders which possess system information, and followers which have no system information using the for…
Efficient and Distributed SINR-based Joint Resource Allocation and Base Station Assignment in Wireless CDMA Networks
Mohammad R. Javan, Ahmad R. Sharafat
We formulate the resource allocation problem for the uplink of code division multiple access (CDMA) networks using a game theoretic framework, propose an efficient and distributed…
