Title: Filtering interference detected at wireless receiver

Abstract: A wireless receiver for UWB or other format receives a useful signal in a particular band of frequencies in spite of interference components. The wireless receiver has two or more different types of tunable band reject filter, involves detecting interference in the received signal, and selecting which of the different types of filter to use according to thresholds of parameters of the detected interference. The filter is then tuned according to the detected interference and the useful signal is then received with the interference suppressed using the selected BRF. As the different types of filters have different drawbacks and benefits, by having multiple types, and selecting which to use according to the detected interference, the filtering can be better matched to the detected interference, or the drawbacks can be reduced for example.
