V2X Communication Systems

Communication between vehicles and vehicles and infra-
structure (V2X) which is one of the significant topics of 5G
development, is a subject of investigations in the Institute.
Part of the research was performed in the framework of
cooperation with Nokia Solutions and Networks. The re-
search team investigated traffic safety, meant as the mini-
mization of vehicle collision probability, in the case of ve-
hicle platoons (convoys) when a wireless communication
system (e.g., IEEE 802.11p) is applied within a moving pla-
toon. The team considered vehicle control algorithms en-
suring reliability and string stability from the system theo-
ry point of view. The next research topic is lengthening the
vehicle platoon by applying so-called virtual communica-
tion leaders. Subsequent research topics are related to
radio resource management algorithms aiming at the minimization of packet collision probability by apply-
ing Mode 3 and 4 LTE system specialized in V2X communications. Recent investigations focus on databases
and edge intelligence to support dynamic spectrum access for vehicle platooning.

Unmanned Aerial Vehicle Communications

Research related to communication with unmanned aerial
vehicles (UAV) concentrate on air to ground radio channel
modeling for both long-range (LOS/NLOS) and medium-
range (LOS) UAV communication systems, physical layer
solutions for control and telemetry radio links with high
reliability and high-speed data links, as well as energy-
efficient solutions for UAV communications. Original syn-
chronization, modulation/demodulation and channel cod-
ing/decoding methods and algorithms are developed and
investigated for the physical layer of UAV communication
systems. The selected solutions are implemented using the
Software Defined Radio (SDR) technique.
