Abstract (300 words maximum)

Accurate estimation of Direction of Arrival (DoA) for safety messages in Vehicle-to-Vehicle (V2V) networks is important for supporting collision avoidance. While single-channel receiver DoA methods are cost-effective and feature low computational complexity to achieve a low angular resolution, on the other hand multi-channel receiver DoA methods feature highly complex systems to achieve a high angular resolution. However, the V2V context does not need a high angular resolution due to the larger dimensions of vehicle compared to their antenna locations. This work develops a novel DoA method utilizing a single-channel receiver method for V2V which uses a three-element antenna array. The antenna elements are amplitude biased such that DoA sensing, and data recovery can take place simultaneously. The system has been shown experimentally to have a high accuracy and low false alarm rate.
