Title: Francedillaois Capman: Innovator in Echo Cancellation Technology
Introduction
Francedillaois Capman is a notable inventor based in Versailles, France. He has made significant contributions to the field of echo cancellation technology, holding a total of three patents. His work has been instrumental in advancing methods that improve audio signal processing.
Latest Patents
Capman's latest patents include an "Echo cancellation method and echo canceller implementing such a process." This innovative method involves inputting a reception signal into an echo generator system, gathering an observation signal, and filtering the reception signal to produce an echo prediction signal. The echo prediction signal is then subtracted from the observation signal to create an error signal. Additionally, the observation signal is decomposed into M spectral components, which relate to different frequencies of the spectrum. M corresponding spectral components of the echo prediction signal are obtained, and M quantities are calculated to represent the degree of similitude between the spectral components. This process allows for spectral shaping of the error signal, adapting the filtering and delivering the output signal from the echo canceller. Another significant patent is the "Acoustical echo canceller with sub-band filtering," which further enhances the capabilities of echo cancellation technology.
