Frequency Selection for Platoon Communications in Secondary Spectrum Using Radio Environment Maps
Marcin Hoffmann, Pawel Kryszkiewicz, Adrian Kliks
Platoon-based driving is an idea that vehicles follow each other at a close distance, in order to increase road throughput and fuel savings. This requires reliable wireless communi…
The Impact of Blocking Cars on Pathloss Within a Platoon: Measurements for 26 GHz Band
Paweł Kryszkiewicz, Adrian Kliks, Paweł Sroka +1
Platooning is considered to be one of the possible prospective implementations of the autonomous driving concept, where the train-of-cars moves together following the platoon leade…
Dynamic Power and Frequency Allocation Scheme for Autonomous Platooning
Paweł Sroka, Adrian Kliks, Michał Sybis +1
In this paper, we consider the use of radio environment maps (REMs) in vehicular dynamic spectrum access (VDSA) for vehicle platooning applications. We propose an algorithm that dy…
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…
Similarity Measures for Location-Dependent MMIMO, 5G Base Stations On/Off Switching Using Radio Environment Map
Marcin Hoffmann, Paweł Kryszkiewicz
The Massive Multiple-Input Multiple-Output (MMIMO) technique together with Heterogeneous Network (Het-Net) deployment enables high throughput of 5G and beyond networks. However, a…
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…
Amplifier-Coupled Tone Reservation for Minimization of OFDM Nonlinear Distortion
Pawel Kryszkiewicz
Nonlinear distortion of an OFDM signal is a serious problem when it comes to energy-efficient Power Amplifier(PA) utilization. Typically, Peak-to-Average Power Ratio(PAPR) reductio…
Increasing Energy Efficiency of Massive-MIMO Network via Base Stations Switching using Reinforcement Learning and Radio Environment Maps
Marcin Hoffmann, Pawel Kryszkiewicz, Adrian Kliks
Energy Efficiency (EE) is of high importance while considering Massive Multiple-Input Multiple-Output (M-MIMO) networks where base stations (BSs) are equipped with an antenna array…
