NOMA-Assisted Grant-Free Transmission: How to Design Pre-Configured SNR Levels?
Zhiguo Ding, Robert Schober, Bayan Sharif +1
An effective way to realize non-orthogonal multiple access (NOMA) assisted grant-free transmission is to first create multiple receive signal-to-noise ratio (SNR) levels and then s…
Optical Non-Orthogonal Multiple Access for Visible Light Communication
Hanaa Marshoud, Sami Muhaidat, Paschalis C. Sofotasios +3
The proliferation of mobile Internet and connected devices, offering a variety of services at different levels of performance, represents a major challenge for the fifth generation…
Optical Adaptive Precoding for Visible Light Communications
Hanaa Marshoud, Paschalis C. Sofotasios, Sami Muhaidat +2
Multiple-input multiple-output (MIMO) techniques have recently demonstrated significant potentials in visible light communications (VLC), as they can overcome the modulation bandwi…
Solutions to Integrals Involving the Marcum Q-Function and Applications
Paschalis C. Sofotasios, Sami Muhaidat, George K. Karagiannidis +1
Novel analytic solutions are derived for integrals that involve the generalized Marcum Q-function, exponential functions and arbitrary powers. Simple closed-form expressions are al…
Wireless Information and Power Transfer in Cooperative Networks with Spatially Random Relays
Z. Ding, I. Krikidis, B. Sharif +1
In this paper, the application of wireless information and power transfer to cooperative networks is investigated, where the relays in the network are randomly located and based on…
Joint Secured and Robust Technique for OFDM Systems
Al-Dweik, M. Mirahmadi, A. Shami +2
This work presents a novel technique for joint secured and robust transmission of orthogonal frequency division multiplexing (OFDM) based communication systems. The proposed system…
