Abstract
Disclosed herein are systems, methods, and devices for time of arrival estimation. Devices include a packet detector configured to identify a data packet included in a received signal having a symbol frequency, and a time stamping unit configured to generate an initial time stamp. Devices also include one or more processors configured to identify an estimated timing of a symbol boundary based on a time of a change in phase of the received signal estimated by using a phase rotation speed and a sample time of an IQ sample of a plurality of IQ samples to compute the time of the change in phase. The one or more processors are also configured to generate an estimated time of arrival based on the initial time stamp, the plurality of IQ samples, and the identified timing of the symbol boundary, wherein the estimated time of arrival is a corrected time of arrival.
