Witryna23 kwi 2015 · A common approach for mitigation such impulsive interference is to apply a memoryless blanking nonlinearity (BN) [3]. Accordingly, a threshold is defined. Any parts of a received signal with a magnitude exceeding this threshold are considered interference and are subsequently blanked. WitrynaA nonparametric approach to signal detection in impulsive interference Abstract: Impulsive interference poses a challenge to conventional detection techniques. The /spl alpha/-stable distribution, while sometimes providing a good model for impulsive interference, has proven to be no exception.

Of these three noise types, the narrow … Witryna15 kwi 2024 · These results are consistent with the theory. Also, we find that the CBF algorithm has weak anti-interference ability, resulting in cluttered background noise and lower resolution, while the VSS-LMS is unable to converge effectively in the presence of impulsive interference, which makes the observed target trajectory blurred.

WitrynaThe model for narrow-band impulsive interference (Class A noise, a subset of the overall model) is next specifically applied to an important class of coherent signal detection problems. Algorithms for error probabilities in optimum detection are then obtained, along with performance bounds, for the same error probabilities.
