Low-Complexity Resource Allocation for Dense Cellular Vehicle-to-Everything (C-V2X) Communications
Mohammad Hossein Bahonar, Mohammad Javad Omidi, Halim Yanikomeroglu
Vehicular communications are the key enabler of traffic reduction and road safety improvement referred to as cellular vehicle-to-everything (C-V2X) communications. Considering the…
Multi-user Joint Maximum-Likelihood Detection in Uplink NOMA-IoT Networks: Removing the Error Floor
Hichem Semira, Ferdi Kara, Hakan Kaya +1
The Internet of Things (IoT) framework requires a massive number of connection thus demanding spectral efficient solutions such as Non-Orthogonal Multiple Access (NOMA). However, t…
Optimal Power Allocation in Downlink Multicarrier NOMA Systems: Theory and Fast Algorithms
Sepehr Rezvani, Eduard A. Jorswieck, Roghayeh Joda +1
In this work, we address the problem of finding globally optimal power allocation strategies to maximize the users sum-rate (SR) as well as system energy efficiency (EE) in the dow…
Two New Kinds of Interference Alignment Schemes for Cellular K-user MIMO Downlink Networks
Jingfu Li, Wenjiang Feng, F. Richard Yu +1
It is known that interference alignment (IA) plays an important role in improving the degree of freedom (DoF) of multi-input and multi-output (MIMO) systems. However, most of the t…
Interplay Between NOMA and GSSK: Detection Strategies and Performance Analysis
Sanjeev Gurugopinath, Sami Muhaidat, Rajaleksmi Kishore +3
Non-orthogonal multiple access (NOMA) is a technology enabler for the fifth generation and beyond networks, which has shown a great flexibility such that it can be readily integrat…
Power Control in Spectrum Sharing Systems with Almost-Zero Inter-System Signaling Overhead
Mohammad Ghadir Khoshkholgh, Halim Yanikomeroglu
Power allocation in spectrum sharing systems is challenging due to excessive interference that the secondary system could impose on the primary system. Therefore, an interference t…
