Abstract :
In this paper, we consider blind interference suppression in IR UWB communication system, and the means of a statistical technique called independent component analysis (ICA), taken as a solution for the coexistence of impulse-radio Ultra-wideband (IR-UWB) systems with other wireless systems was studied. Particularly for the evaluation of the system performance, tone, multiton, and partial-band interference signals are considered at very low signal to interference ratio. The performances showed that ICA is a very good method for interference suppression in IR-UWB system.
