Research On Alternative Diversity Aspects foR Trucks

 

Welcome to the ROADART Project!

With the investigation of future-oriented diversity and beamforming techniques the resulting ROADART platform will assure a sustainable and holistic approach for corporative ITS systems in a way that state-of-the-art systems cannot provide. The main objectives are:

  • Perform measurements for Truck-to-Truck, Truck-to-Infrastructure mobile radio channel conditions.
  • Perform full statistical characterization of ROADART-specific multi-antenna radio channels.
  • Develop novel radio channel models (both stochastic geometric and ray tracing models) for T2T and T2I channels with support of multiple antenna systems.
  • Investigate multiple antenna diversity techniques in order to provide increased throughput and reliability in T2T/T2I wireless links.
  • Evaluate the use of beamforming for T2T/T2I communications with the proposal of possible new elements to existing vehicular communication standards. Moreover, the use of parasitic antennas will be assessed in order to increase multi-antenna functionalities with minimum interventions on the Truck structure.
  • Introduce spatial modulation as a transmission technique for improved vehicular radio communications.
  • Analyze antenna array aspects for T2T/T2I communication links, including the number of elements, the type of antennas, the introduction of parasitic antennas, antenna placement and mounting on the trucks, as well as antenna structures for the infrastructure especially for special use cases e.g. tunnels.
  • Investigate communication system improvement through cooperative techniques and relays, focusing especially in the T2T relaying for platooning systems and coordinated multi-point T2T/T2I reception.
  • Develop novel localization and detection techniques for conditions where Satellite global navigation systems are not applicable, such as tunnels, using cooperative and adaptive communication techniques as well as sensor measurements and information from infrastructure.
  • All the proposed techniques will be extensively evaluated through simulation using the realistic, measurement-based ROADARD channel models.
  • Cooperative Adaptive Cruise Control, a safety-critical application, will be implemented on a truck, to evaluate the theoretical results and to support the measurements. Herewith, a safety approach for increasing robustness w.r.t. wireless communication impairments on the application layer will be developed and implemented.
  • Based on the results and conclusions, a novel multi-antenna T2T/T2I communication platform will be developed that will achieve optimized and reliable use of the radio channels in order to provide T2T/T2I services in terms of safety, traffic/route control, transportation efficiency and environmental awareness, while taking into account practical issues regarding the installation of complicated communication systems on heavy-duty vehicles.

The developed platform will be demonstrated and evaluated for specific scenarios that include special use cases, i.e. tunnels and platooning.

Radio Channel Measurements

The ROADART T2X channel modeling task was based on wideband multidimensional channel measurements at 5.9 GHz ITS frequency band. Three channel measurement campaigns were undertaken; two in Germany and one in Greece.

 

Measurement Campaign, Peloponnese Greece, 10/2017

The third measurement campaign took place in Panagopoula tunnel, a 3.179 meters long tunnel located in Peloponnese-Greece. The setup of the measurement equipment was designed in a way that one can measure a more generic channel that is free of shadowing in T2I links. The channel sounder used could measure a 2×4 MIMO channel with a signal bandwidth of 25 MHz. The excitation signal was an OFDM-like transmitting signal with the subcarriers uniformly distributed in the measurement bandwidth and it was generated using Frank-Zadoff-Chu sequences. The signal was cyclically extended. The technique that was used for the MIMO measurement procedure is a popular fast switching method with a time division basic principle scheme that alternates between the transmitting antennas for each one of the receiving antennas.

 

Measurement Campaign, Duesseldorf, 04/2017

The second measurement campaign took place in Kamp-Lintfort, in North Rhine-Westphalia. The measurement equipment setup was designed in order to measure a more generic channel that is free of shadowing in T2T and T2I links. Therefore, to avoid the signal blocking by the vehicle structures, the antennas were placed well-above the roof of two vehicles, at a height similar to the one used in the first measurement campaign, using car roof racks and machined custom-made equipment. The channel sounder used could measure a 2×4 MIMO channel with a signal bandwidth of 500 MHz. Due to the unavailability of two baseband generators, a different set of excitation waveforms were used. The measurement routes that were followed included mainly a highway with varying traffic density along its route, two fairly long tunnels and some areas with smaller roads.

 

Measurement Campaign, Munich, 10/2016

The first campaign took place in the outskirts of Munich, in the district of Dachau, Bavaria.The measurement setup and the placement of the antenna array on the trucks considered the impact of the truck container and the corresponding shadowing of the signal. The channel sounder used could measure a 2×8 MIMO channel with a signal bandwidth of 500 MHz. The excitation signal is an OFDM-like transmitting signal with the subcarriers uniformly distributed in the measurement bandwidth and it is generated using Frank-Zadoff-Chu sequences. The signal is cyclically extended. The technique that was used for the MIMO measurement procedure is a popular fast switching method with a time division basic principle scheme that alternates between the transmitting antennas for each one of the tetrad of the receiving antennas. After the reception of ten frames from the first tetrad, RF switch was taking place, and another ten frames were received from the second tetrad. The overall sequence contains 7000 samples with a sampling frequency of 7 GSamples/sec. The routes followed included mainly a highway with varying traffic density along its path, a fairly long tunnel, and some areas with smaller roads that were used for maneuvering the trucks in order to get back to the highway.
