Introduction

Frederic Fernez is a notable inventor based in Fontenilles, France. He has made significant contributions to the field of digital signal processing, holding 2 patents that showcase his innovative approach to technology.

Latest Patents

Fernez's latest patents include methods and apparatus for processing digital composite signals. These embodiments involve techniques for processing a digital composite signal generated at a first sampling rate. The signal comprises at least first and second carrier-bands, which define a first inner gap between them. This gap includes a first gap between the highest frequency of the first carrier-band and the lowest frequency of the second carrier-band. The digital composite signal has a predetermined instantaneous bandwidth that is lower than a sampling bandwidth. An outer gap is determined outside the instantaneous bandwidth and within the sampling bandwidth. The first inner gap is reduced to define a second inner gap, with its width related to the width of the outer gap. The resulting folded digital composite signal is decimated to a second sampling rate lower than the first, creating a decimated folded digital composite signal.

Another significant patent is a digital front-end channelization device for one or more carrier signals. This device comprises a per carrier section and a composite section. The composite section includes signal processing units, which may feature an inverse Fourier transform unit for transforming a composite carrier signal into a time domain signal. It also includes a sample detection and selection unit for detecting and selecting a peak of the time domain signal, a clipping unit for producing an error signal, and a Fourier transform unit for transforming the error signal into a frequency domain error signal. Additionally, it has a frequency shaping unit, a summation unit for subtracting the frequency shaped error signal from the composite carrier signal, and a phase selection unit for phase adjustment of the resulting signal.
