Title: Gaetan Guillaume: Innovator in Digital Demodulation Technology

Introduction

Gaetan Guillaume is a notable inventor based in Laille, France. He has made significant contributions to the field of digital demodulation technology, holding 2 patents that showcase his innovative approach to improving receiver systems.

Latest Patents

One of his latest patents is titled "Memory-aided synchronization in a receiver." This invention involves a method that includes storing information from a first frame of an incoming broadcast signal in a memory coupled to a demodulator. It decodes a first preamble symbol of the first frame to determine a transmission mode. The method accesses some of the stored information from the memory and decodes at least one second preamble symbol of the first frame from the accessed information to determine pilot pattern information. Finally, it receives data symbols of the first frame and synchronizes the demodulator based on the received data samples and the pilot pattern information.

Another significant patent is the "Multi-standard digital demodulator for TV signals broadcast over cable, satellite and terrestrial networks." This invention provides a multi-standard single-chip receiver for digital demodulation of TV signals broadcasted over various digital television means, such as satellite, cable, and terrestrial. The receiver can receive and demodulate a variety of different signal types from one or more up-front tuners. The demodulator architecture can be optimized to re-use common demodulation processing blocks for the different incoming signal types.
