This separation has significant advantages in practical implementations and suggests extensions to other beamformer structures.作者: 和平主義 時(shí)間: 2025-3-22 00:49

Error and Reject Tradeoff for Nearest Neighbor Decision Rules has a probability of error which is no greater than twice the Bayes probability of error. They also showed that the error probability of the k-nearest neighbor (k-NN) rule is monotonically decreasing in k to the Bayes error probability. The family of k-NN rules is therefore quite versatile, extendi作者: Offstage 時(shí)間: 2025-3-24 22:41 作者: GLOSS 時(shí)間: 2025-3-25 02:16

Optimum Antenna Processing: A Modular ApproachWe have N+1 sensors with which we want to detect or to estimate a plane wave signal imbedded in noises. We assume that sensors have been correctly delayed such that the signal components are identical on all sensors.
