“…Smart antenna systems installed on a DSRC-equipped vehicle can measure the delayed arrival of a signal between similar antennas in the system in order to measure the bearing angle to a LOS transmitter [10], even under poor visibility conditions. Phased array antenna technology is one such implementation used to measure the bearing angle, also known as the Angle of Arrival (AoA).…”

Vehicle-2-Vehicle safety applications using Dedicated Short Range Communication (DSRC) radios allow automobiles to exchange Basic Safety Messages (BSMs) to avoid automotive collisions. Most of these applications rely on GPS and integrated on-board sensors to obtain the position and motion information that is transmitted in a BSM. In the event that the BSM contents are compromised (i.e. hacking), providing an alternative method to detect impending collisions is critical. This paper proposes a creative architecture that uses omni-directional antennas to achieve 3D localization and employs Doppler domain analysis to determine the threat of collision, without changing any existing DSRC protocols. Through rigorous mathematical modeling and simulations, the feasibility of this architecture can correctly predict a head-on collision with an accuracy up to 60.87% and an optimal false alarm rate as low as of 41.70%.

“…However, receive beamforming requires expensive and synchronized hardware equipment in addition to high computational complexity of AoA estimation. The use of directional antennas at the vehicles is a well-known [9] alternative to beamforming. Its implementation is much simpler though it presents limitations of the available pointing directions.…”

Cellular networks will be one of the main pillars in the development of future vehicular communications. However, downlink (DL) and uplink (UL) channels must be improved to cope with the required reliability and high throughput of the coming vehicular use cases. Vehicle side solutions which benefit from the high antenna gains could improve the performance of the UL channel whose coverage is limited by UL transmit power. In this paper we experimentally evaluate the performance of a directional antennas switching system based on live Long Term Evolution (LTE) measurements. A total of more than 150 km have been driven comprising different radio propagation scenarios. The results show considerable improvements of Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ), together with a reduction of handovers specially in scenarios with high Line-Of-Sight probability. Additionally, it has been found that the UL throughput does not improve with the increase of antenna gain probably due to the UL Power Control mechanism used in LTE.

“…However, the vehicle is influenced from continuous disturbances during the operations, and its dynamics is described as a class of nonlinear systems because the relative position and angle between the vehicle and the target undergo large variations in a short period. From the viewpoint of the radio communication field, several schemes have been proposed to the problem (2), (4), (5) . Our first objective is to propose an optimal controller design method for the precise pointing of the mobile antenna under continuous disturbances.…”

This paper describes a pointing control of a mobile antenna mounted on a vehicle. For precise pointing, the antenna must be controlled to point to a target under the influence of continuous disturbances acting on the vehicle. For this purpose, we propose an optimal controller design method in a framework of the H ∞ gain-scheduled controller synthesis. By this synthesis, the optimal controller is obtained by using parameter varying notch-filter in order to attenuate the various frequency disturbances. We apply this design method to an automobile model having a rotating antenna.In this section, we propose an optimal controller design method by using the parameter varying notch filter. First, fundamental ideas of two filters of the parameter varying notch filter and the low-pass filter are described. Next, the structure of the generalized plant including both filters is shown, and the H ∞ gain-scheduled controller design method is applied to this plant.
