Abstract

A method for performing ultra-wide-band (UWB) radio-frequency (RF) frame validation, wherein an UWB frame comprises: a synchronisation header (SYNC) field suitable for synchronisation between a transmitter and a receiver, and a scrambled timestamp sequence (STS) suitable for providing additional integrity and security for ranging measurements. The method comprises: receiving a SYNC channel impulse response (CIR) of an UWB frame; receiving an STS CIR of the UWB frame; comparing peak amplitude values of the SYNC CIR and the STS CIR. If a difference between the peak amplitude values of the SYNC CIR and the STS CIR is greater than a predetermined magnitude difference threshold, then: rejecting the UWB frame; else: comparing polarities of the SYNC CIR and the STS CIR. If the polarities of the SYNC CIR and the STS CIR are different, then rejecting the UWB frame; else: accepting the UWB frame.
