A system, method, and computer program product for removing “narrowband” interference from a broader spectrum containing a UWB signal, in a receiver of the UWB signal. The RFI is extracted from a broader spectrum to remove interference from the UWB signal, by employing an impulse response in a radio front-end of the UWB receiver that is matched with an incoming wavelet employed as part of a UWB signal to be received, matching the impulse response to the wavelet and its time-shifted and inverted versions, passing the wavelet unscathed through the receiver, and excising narrowband signals (continuous tones). Exemplary embodiments for the RFI extraction mechanism include a transmission line circuit, an active transmission line circuit, and an adaptable, controllable phase delay circuit.

A combination of a low flexural modulus and low crystallinity polyolefin and a functionalized polyolefin were found to result in an olefin composition with excellent adhesion to metals and polar polymers (e.g. polyesters, polyamides, etc) especially fibers therefrom. When these two polyolefins were added to a thermoplastic vulcanizate (e.g. used to partially or fully replace the semicrystalline polyolefin of a thermoplastic vulcanizate), the thermoplastic vulcanizate was found to have the necessary adhesion to form fiber reinforced thermoplastic vulcanizate.
