Latest Patents
Lacroix's latest patents include a method for computing fast Fourier transform and inverse fast Fourier transform. This method calculates the fast Fourier transform or the inverse fast Fourier transform of a series of N real samples x(n), where N is a power of two. It operates according to a time interleaving algorithm and provides the sample series X(n) in ascending order to index n, utilizing limited calculating storage means. Another significant patent involves a process for estimating a parasite phase shift during the reception of a multi-carrier signal. This method estimates an interference phase shift when receiving a multicarrier signal formed of a time series of symbols modulating multiple carrier frequencies. The phase variation between symbols bearing reference elements is estimated by analyzing these elements, with each reference element weighted by information representing the noise affecting the carrier frequency.
