Abstract: An RF device includes a first channel with a first frequency band, configured to receive a first signal; and a second channel with a second frequency band, configured to receive a second signal. The first frequency band and the second frequency band are different. The device includes control circuitry configured to obtain a first channel response associated with the received first signal at the first channel, to obtain a second channel response associated with the received second signal at the second channel and to calibrate the first channel response and the second channel response by steering to a calibration base. The control circuitry is further configured to calibrate the first channel response and second channel response by channel stitching to obtain a combined channel response.

Abstract: In accordance with a first aspect of the present disclosure, an ultra-wideband (UWB) receiver is provided, comprising: an attack mitigation unit configured to mitigate one or more attacks on a correlation function; a correlation unit configured to perform the correlation function by correlating an input signal received by the UWB receiver with a predefined sequence and to generate a correlation output based on correlating said input signal with the predefined sequence; and a first path detection unit configured to receive the correlation output and to detect a first path by evaluating the correlator output during a correlation window, said correlation window being a predefined period of time. In accordance with a second aspect of the present disclosure, a corresponding method of operating a UWB receiver is conceived. In accordance with a third aspect of the present disclosure, a computer program is provided for carrying out said method.
