발명의 명칭: (EN) SYSTEM AND METHOD FOR MODULATING FILTER COEFFICENTS IN A CHANNELIZER
(FR) SYSTÈME ET PROCÉDÉ DE MODULATION DE COEFFICIENTS DE FILTRE DANS UN CANALISEUR
요약서:
(EN) Circuit and method for modulating filter coefficients of a frequency channelizer having a filter bank include: receiving a wide spectrum input signal; modulating the filter coefficients of the filter bank to sweep a center frequency of each channel of the frequency channelizer, using a modulation scheme; and inputting frequency offset compensation caused by the modulation, and output signals of the frequency channelizer to an application processing circuit to convert the output signals to their original center frequencies. A dynamically configurable filter bank is proposed where the filter coefficients are regularly modulated (frequency modulated) so that the center frequencies of the filters are variable and such that a passband is located where previously a spectral gap was present in the filter bank.
(FR) Selon l'invention, un circuit et un procédé de modulation de coefficients de filtre d'un canaliseur de fréquence comportant une banque de filtres consistent à : recevoir un signal d'entrée à large spectre; moduler les coefficients de filtre de la banque de filtres pour balayer une fréquence centrale de chaque canal du canaliseur de fréquence, en utilisant un schéma de modulation; et entrer une compensation de décalage de fréquence provoqué par la modulation, et fournir des signaux du canaliseur de fréquence à un circuit de traitement d'application pour ramener les signaux de sortie à leurs fréquences centrales d'origine. L'invention concerne une banque de filtres configurable de manière dynamique où les coefficients de filtre sont modulés de manière régulière (modulés en fréquence) de sorte que les fréquences centrales des filtres soient variables et de sorte qu'une bande passante soit située où un creux spectral était présent auparavant dans la banque de filtres.
