Based on Teager-Kaiser(TK) power computation operator, the novel coexisting narrow band interference(NBI) detecting algorithm for Ultra-wideband(UWB) communications is proposed in this paper. The novel algorithm can estimate the central frequency of NBI accurately by adding the standard frequency analog signal to the TK processing branch and using the discrepancy frequency information provided by...
In this paper, a novel approach to interference mitigation with coexisting spectrum users for UWB pulse radio is proposed. This new approach uses adaptive frequency spectrum estimator to give the estimating values of each coexisting spectrum users' center frequency and band. Based on these estimating values, the frequency band of UWB communication system can be adaptively divided into multibands....
