Abstract:
Systems, methods, apparatuses, and computer readable media are disclosed for providing interference rejection in ultra-wideband real time locating systems. In one embodiment, an ultra-wideband (UWB) receiver is configured to: receive a composite signal, the composite signal comprising a UWB signal transmitted from within a monitored region and an interference signal transmitted from a source positioned outside the monitored region; filtering at least a first component of the composite signal representing the interference signal with a tunable notch filter to generate a filtered signal; determining an interference level in the filtered signal; and adjust the tunable notch filter to reduce the interference level. Corresponding systems, methods, and computer-readable storage medium are also provided.
