Title
On the modified Teager-Kaiser energy operator regarding narrowband interference
Abstract
This paper analyzes a modified Teager-Kaiser energy operator under narrowband interference within a subband of a multiband impulse radio UWB system. It is shown that a simple weighting of the Teager-Kaiser operator results in a significant frequency dependent energy distribution of the received signal. Hence, the modified Teager-Kaiser operator is not only a DC shifter. In comparison to the traditional Teager-Kaiser operator, a considerable increase of the amplitude spectrum around twice the subband's carrier frequency occurs at its output, which can improve the detection performance in absence or in presence of narrowband interference.
