Devices include a packet detector configured to identify a data packet included in a received signal having a symbol frequency. Devices also include a time stamping unit configured to generate an initial time stamp in response to the packet detector identifying the data packet. Devices further include an IQ capture unit configured to acquire a plurality of IQ samples representing phase features of the received signal. Devices additionally include a processing unit that includes one or more processors configured to generate an estimated time of arrival based on the initial time stamp and the plurality of IQ samples."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Time of arrival estimation for Bluetooth systems and devices","description":"Disclosed herein are systems, methods, and devices for time of arrival estimation in wireless systems and devices.
