ROADART :: Diversity Engine

In ROADART, a novel Diversity Engine tailored-made for Truck-to-Truck (T2T) and Truck-to-Infrastructure (T2I) Communications was developed. The antenna (or spatial) diversity was used as the base of the diversity engine and additionally, a beampattern selection scheme was implemented with the use of reconfigurable antennas. The beampattern selection scheme was able to produce an omnidirectional pattern for broadcast – multicast transmission/reception as well as a directive pattern that can improve performance for several applications like CACC and platooning. The hybrid spatial-beamspace diversity scheme was implemented with the use of ESPAR Antennas with pattern selection capabilities.
