Self-Calibration for Massive MIMO with Channel Reciprocity and Channel Estimation Errors
De Mi, Lei Zhang, Mehrdad Dianati +3
In time-division-duplexing (TDD) massive multiple-input multiple-output (MIMO) systems, channel reciprocity is exploited to overcome the overwhelming pilot training and the feedbac…
Non-Orthogonal Multiple Access for Visible Light Communications with Ambient Light and User Mobility
Rangeet Mitra, Paschalis. C. Sofotasios, Vimal Bhatia +1
The ever-increasing demand for high data-rate applications and the proliferation of connected devices pose several theoretical and technological challenges for the fifth generation…
Cache-Aided Non-Orthogonal Multiple Access for 5G-Enabled Vehicular Networks
Sanjeev Gurugopinath, Paschalis C. Sofotasios, Yousof Al-Hammadi +1
The increasing demand for rich multimedia services and the emergence of the Internet-of-Things (IoT) pose challenging requirements for the next generation vehicular networks. Such…
Energy Efficiency Analysis of Collaborative Compressive Sensing Scheme in Cognitive Radio Networks
Rajalekshmi Kishore, Sanjeev Gurugopinath, Sami Muhaidat +3
In this paper, we investigate the energy efficiency of conventional collaborative compressive sensing (CCCS) scheme, focusing on balancing the tradeoff between energy efficiency an…
Sensing-Throughput Tradeoff for Superior Selective Reporting-based Spectrum Sensing in Energy Harvesting HCRNs
Rajalekshmi Kishore, Sanjeev Gurugopinath, Sami Muhaidat +3
In this paper, we investigate the performance of conventional cooperative sensing (CCS) and superior selective reporting (SSR)-based cooperative sensing in an energy harvesting-ena…
Opportunistic Ambient Backscatter Communication in RF-Powered Cognitive Radio Networks
Rajalekshmi Kishore, Sanjeev Gurugopinath, Paschalis C. Sofotasios +2
In the present contribution, we propose a novel opportunistic ambient backscatter communication (ABC) framework for radio frequency (RF)-powered cognitive radio (CR) networks. This…
On the Sum of Fisher-Snedecor F Variates and its Application to Maximal-Ratio Combining
Osamah. S. Badarneh, Daniel B. da Costa, Paschalis C. Sofotasios +2
Capitalizing on the recently proposed Fisher-Snedecor F composite fading model, in this letter, we investigate the sum of independent but not identically distributed (i.n.i.d.) Fis…
