Abstract
Systems, methods, and circuitries are provided for determining the likelihood that a malicious signal component is present in a UWB signal. In one example, a UWB receiver device is configured to receive a UWB signal during a ranging round; correlate the received UWB signal with a reference STS template to generate a correlation output; based on the correlation output, compute a channel quality indicator that characterizes a noise level of the channel; compute an attack-detection figure of merit (A-D FOM) based on the channel quality indicator, a block error of the received UWB signal, or a frequency error of the received UWB signal; and provide data indicative of the A-D FOM to a controller device.
