Capacity enhancement in vehicle to roadside networks using ESPAR technique

In this paper, we investigate electronically steerable parasitic array radiator (ESPAR) smart antenna in a highway scenario, where roadside access points (APs) are installed on a highway to provide intelligent transportation System (ITS) services. We Consider vehicle-to-roadside (V2R) communication for a vehicle that aims to send data to the AP (uplink). A seven element ESPAR system as a beam former smart antenna in AP is used to eliminate the interference signals. The simulation results indicate that ESPAR system can improve the average capacity of the link more than 2 bps/Hz.
