Abstract: A method of filtering in sub-bands that eliminates or greatly restricts aliasing effects is disclosed. First, a source digital signal is transformed into at least two distinct frequency sub-bands. Next, each of the frequency sub-bands is filter processed. The filter processing includes the steps of defining an overall filtering profile, determining a set of partial filtering profiles each associated with one of the sub-bands, and filtering each of the sub-bands according to the associated partial filtering profile. Finally, the filtered sub-bands are reverse transformed to deliver a reconstructed filtered signal. The determined partial filtering profiles are applied so that the reconstructed filtered signal corresponds substantially to a forward filtering of the source digital signal according to the overall filtering profile. In particular, the partial filtering profiles are applied such that the aliasing terms still present after filtering are substantially compensated for.

Abstract: An antenna comprises a quarter-wavelength skirt antenna adapted to be disposed over an artificial ground and comprising a vertical cylindrical tube closed at the upper end and a coaxial feed inside the tube. The radiation pattern of the skirt antenna is essentially omnidirectional with a low elevation angle. The skirt antenna is combined with a helical antenna disposed vertically above the skirt antenna and coaxially therewith. The surface closing the upper part of the tube of the skirt antenna constitutes a reflective plane for the helical antenna favoring a hybrid radiation mode specific to the latter, partially axial and partially radial, by lowering the receive lobe of the radiation pattern towards an elevation angle suitable for receiving signals transmitted via satellite. A coupling device combines the signals received by each of the two antennas and feeds them to a common coaxial line.

Abstract: A method and apparatus for the coherent demodulation of a digital signal constituted by digital elements distributed in the time-frequency space and transmitted in the form of symbols constituted by a multiplex of N orthogonal carrier frequencies modulated by a set of said digital elements and broadcast simultaneously, the digital signal also including reference elements having a known value position in said time frequency space. The method includes a Fourier transform of at least samples of said digital signal containing said reference elements from a frequency domain into a temporal domain, a weighting of the transformed samples in the temporal domain by a rectangular temporal window f.sub.n, a thresholding of the transformed samples in the temporal domain to eliminate any samples below a predetermined threshold, and a reverse Fourier transform of the samples remaining after said weighting and thresholding from the temporal domain into the frequency domain for projection onto said digital signal. The threshold level can be fixed or varied based on the power level of the noise affecting the transmission channel or an estimated pulse response of the transmission channel.

Abstract: The present invention concerns a method for processing an etched surface of a semiconductive or semi-insulating substrate. It further concerns integrated circuits manufactured by this method and an anodic oxidation apparatus for implementing the method. The invention is particularly applicable to the manufacture of integrated circuits with ultrafine details (below 1.mu.) and in particular to manufacturing electro-optical devices. Anodic oxidation with controlled voltage and current is used to peel a constant thickness of oxidation off a surface of the substrate so as to improve the subsequent epitaxial growth.
