- W2034348713 abstract "A suboptimum quantization-detection system in which the locally optimum nonlinearity is replaced by a uniform quantizer and a coder for the uniform quantizer output levels is proposed. The proposed detection system does not require iterations to obtain the parameters of the quantizer and is easily implementable in practice. We develop a design procedure of the suboptimum quantizer and obtain the parameters of the suboptimum quantizer for the generalized Gaussian noise density. We also compare the performance of the suboptimum quantization detector with that of other detectors. Es wird ein suboptimales Verfahren zur Detektion durch Quantisierung vorgeschlagen, in dem die lokal optimale Nichtlinearität durch einen gleichförmigen Quantisierer und einen Codierer für die gleichförmig quantisierten Ausgangswerte ersetzt wird. Das vorgeschlagene Detektionssystem erfordert keine iterative Bestimmung der Parameter des Quantisierers und ist in der Praxis leicht zu implementieren. Es wird ein Entwurfsverfahren für den suboptimalen Quantisierer entwickelt, aus dem man die Parameter des Quantisierers für gauβsche Störsignale erhält. Die Eigenschafteb des suboptimalen Detektors werden mit denen anderer Detektoren verglichen. On propose un système de quantification-détection suboptimal dnas lequel la non-linéarité localement optimale est remplacée par un quantificateur uniforme et un codeur des niveaux de sortie du quantificateur. Le système de détection proposé ne nécessite pas d'itération pour obtenir les paramètres du quantificateur et donc facilement réalisable en pratique. Nous développons une procédure de conception du quantificateur suboptimal et obtenons les paramètres de ce quatificateur pour la densité de bruit gaussien généralisé. Nous comparons également les performances du détecteur quantifié suboptimal avec celle des autres détecteurs." @default.
