A method for adaptively setting the threshold of an energy detector for Ultra-Wideband radio systems is presented in this paper. The method, which is suitable for low-complexity and low-cost implementation, is based on the estimation of the input noise and interference power. Simulations and experimental results obtained from a prototype UWB system show that the proposed method can adaptively set the threshold of the detector. Therefore it is robust to changes in the interference power, and it can limit the false alarm rate.

Abstract
A method for adaptively setting the threshold of an energy detector for Ultra-Wideband radio systems is presented in this paper. The method, which is suitable for low-complexity and low-cost implementation, is based on the estimation of the input noise and interference power. Simulations and experimental results obtained from a prototype UWB system show that the proposed method can adaptively set the threshold of the detector. Therefore it is robust to changes in the interference power, and it can limit the false alarm rate.File in questo prodotto:
