The transceiver is configured to, during a current connection event, monitor notification messages transmitted from a portable access device to a phone-as-a-key (PaaK) system of a vehicle, where the notification messages are transmitted to establish a communication link between the portable access device and the PaaK system. The control module is configured to: perform an in-phase and quadrature phase capture of the notification messages based on fields in one or more of the notification messages, where the fields include a mobile de-whitened section including two or more series of consecutive bits, where the consecutive bits in each of the one or more series are all zeros or all ones; based on the in-phase and quadrature phase capture, determine an angle-of-arrival of the notification messages, and indicate the angle-of-arrival to the PaaK system for permitted access determined by the PaaK system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Antenna switching control for AOA capturing in phone-as-a-key systems with de-whitened tone transmission, CRC based validation and event timing","description":"A reader includes a transceiver and a control module.
