Analog signal separator for UWB versus narrowband signals

An ultrawide bandwidth receiver comprising:

• an input terminal configured to receive an incoming signal including an ultrawide bandwidth signal and a narrowband signal that overlap in frequency;
• an interference extraction circuit for receiving the incoming signal from the input terminal and providing an output signal to an extraction circuit output terminal, the interference extraction circuit being configured to have an impulse response including:
• a first component that has a first impulsive shape, and at least one other component delayed in time from the first component, and having a second impulsive shape;
• and
• an ultrawide bandwidth signal detector connected to the extraction circuit output terminal, and configured to detect the ultrawide bandwidth signal,
• wherein the interference extraction circuit allows energy from the ultrawide bandwidth signal to be conveyed to the extraction circuit output terminal and substantially blocks energy from the narrowband interference signal from being output to the extraction circuit output terminal.

A radio frequency interference extraction mechanism in a radio end of an ultrawide bandwidth receiver, comprising:

• an input node for receiving an ultrawide bandwidth signal;
• a time-shifting circuit for time-shifting the received ultrawide bandwidth signal to create a time-shifted ultrawide bandwidth signal;
• and
• a summer for adding the time-shifted ultrawide bandwidth signal and the received ultrawide bandwidth signal to form an adjusted signal.

A radio frequency interference extraction mechanism for receiving an incoming ultrawide bandwidth signal and providing an adjusted ultrawide bandwidth signal that has any narrowband interference signal that coincides with the ultrawide bandwidth signal in frequency suppressed, comprising:

• a radio front end, having an impulse response including a first impulse response component and a second impulse response component, for receiving the incoming ultrawide bandwidth signal and generating the adjusted ultrawide bandwidth signal;
• a controller configured to control the radio front end to adjust a relative position of the first impulse response component and the second impulse response component;
• and
• a control receiver configured to detect at least one of a signal energy level and a signal to noise ratio of the narrowband interference signal and to provide an indication to the controller regarding a characteristic feature of the narrowband interference signal.
