ELECTRONIC DEVICE METHOD AND COMPUTER-READABLE MEDIUM UTILIZING PULSE SHAPING INTEROPERABILITY PROTOCOL FOR ULTRA WIDEBAND SYSTEMS

摘要

Embodiments allow communicating ultra wideband (UWB) devices to collaborate by exchanging pulse shape information. UWB devices use pulse shape information to improve ranging accuracy. The improved ranging accuracy can be used in a complex multi-path environment where advanced estimation techniques are used to extract the arrival path for time-of-flight (ToF) estimation. To determine the pulse shape information to be shared, some embodiments include determining the location information of the UWB device, and selecting pulse shape information that satisfies the regional aspect. The pulse shape information includes a time-zero index specific to the ranging signal used by the UWB receiver to set a timestamp for time-of-flight (ToF) calculation. Some embodiments include measuring performance characteristics and selecting different pulse shape information based on performance characteristics for improved accuracy.
