Abstract :
In this paper, we design a novel energy-detection based receiver architecture to detect unknown UWB signals in a strong narrowband interference (NBI) environment. Designed receiver is capable of suppressing NBI at low cost without any need for searching its frequency location. This is made possible by preprocessing the received signal using a cascaded nonlinear energy operator followed by a high-pass filter before regular energy detection.
