MULTIPLE ANTENNA INTERFERENCE REJECTION IN ULTRA-WIDEBAND REAL TIME LOCATING SYSTEMS
First Claim
1. A method for providing interference rejection, the method comprising:
- receiving an interference signal from a source positioned outside a monitored region;
receiving a composite signal transmitted from a tagged object moving about a playing field within the monitored region, wherein the composite signal comprises a location signal and a component of the interference signal;
detecting whether the component of the interference signal exceeds a threshold value; and
adjusting, via a processor, filtering of the composite signal to attenuate the component of the interference signal based on the detecting whether the component of the interference signal exceeds the threshold value.

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 an interference signal from a source positioned outside a monitored region; receive a composite signal transmitted from a tagged object moving about a playing field within the monitored region, wherein the composite signal comprises a location signal and a component of the interference signal; detect whether the component of the interference signal exceeds a threshold value; and adjust, via a processor, filtering of the composite signal to attenuate the component of the interference signal based on whether the component of the interference signal exceeds the threshold value. Some embodiments provide for filtering of the composite signal using a combiner while others employ a tunable notch filter. Corresponding systems, methods, and computer-readable storage medium are also provided.
