摘要： There is described a method of verifying a time-of-flight based ranging result in a UWB ranging device, the method comprising: exchanging a sequence of messages between the UWB ranging device and a further UWB ranging device as part of a double-sided ranging process to obtain round times and response times at both the UWB ranging device and the further UWB ranging device; estimating a time-of-flight value based on the round times and response times; and verifying the ranging result by performing a consistency check based on the estimated time-of-flight value and one or more predetermined parameter values. Furthermore, a UWB ranging device and a UWB ranging system are described.

摘要： A processing module for a receiver device configured to provide for processing of a signal received by the receiver device from a transmitter device, the signal comprising a secure training sequence divided into a plurality of time spaced blocks, the secure training sequence comprising a non-repeating pattern of symbols, and wherein one of:
a) at least a first block is transmitted from a first antenna and a second block is transmitted from a different second antenna of the transmitter device;
b) at least a first block is received by a first antenna and a second block is received by a different second antenna of the receiver device;
wherein the processing module is configured to:
based on a first phase marker in the first block and a second phase marker in the second block defining a phase difference of the signal between the first and second antennas and a known spacing of the first antenna relative to the second antenna, determine an angle of arrival of the signal relative to the receiver device.

摘要： The disclosure relates to a processing module of a receiver device and associated method and apparatus. It deals with carrier recovery (phase and symbol synchronization) for Impulse-Radio Ultra-Wideband systems (IR-UWB) like in the IEEE 802.15.4 standard. The method comprises receiving a signal comprising one or more frames, each frame comprising a synchronization-symbol-portion, a security-sequence-portion, and a data-payload-portion; and processing the signal to perform carrier recovery, and excluding at least part of the security-sequence-portions of the one or more frames from the carrier recovery process. An alternative preamble structure with an interleaved pattern of Secure Training Sequence and Resynchronization Portions is disclosed
