Beyond 5G: Big Data Processing for Better Spectrum Utilization
Adrian Kliks, Łukasz Kułacz, Paweł Kryszkiewicz +5
This article emphasizes the great potential of big data processing for advanced user- and situation-oriented, so context-aware resource utilization in future wireless networks. In…
Coopetition methodology for resource sharing in distributed OFDM-based cognitive radio networks
Marcin Parzy, Hanna Bogucka
In this paper, we present a distributed resource allocation mechanism in cognitive radio networks, based on a new coopeti-tion methodology, which combines advantages of nodes compe…
Out-of-Band Power Reduction in NC-OFDM with Optimized Cancellation Carriers Selection
Pawel Kryszkiewicz, Hanna Bogucka
In this letter, we propose a computationally efficient method for joint selection of cancellation carriers (CCs) and calculation of their values minimizing the out-of-band (OOB) po…
Energy Savings by Task Offloading to a Fog Considering Radio Front-End Characteristics
Pawel Kryszkiewicz, Filip Idzikowski, Bartosz Bossy +2
Fog computing can be used to offload computationally intensive tasks from battery powered Internet of Things (IoT) devices. Although it reduces energy required for computations in…
In-Band-Interference Robust Synchronization Algorithm for an NC-OFDM System
Pawel Kryszkiewicz, Hanna Bogucka
We consider receiver synchronization in the non-continguous orthogonal frequency division multiplexing (NC-OFDM)-based radio system in the presence of in-band interfering signal, w…
Low Complex, Narrowband-Interference Robust Synchronization for NC-OFDM Cognitive Radio
Pawel Kryszkiewicz, Hanna Bogucka
This paper presents a new, low-complexity algorithm for time and frequency synchronization in a non-contiguous-orthogonal frequency division multiplexing (NC-OFDM) radio communicat…
