Title: Boualem Boashash: Innovator in Time-Frequency Signal Analysis
Introduction
Boualem Boashash is a noted inventor currently based in Queensland, Australia. He has made significant contributions to the field of signal processing, specifically in developing advanced techniques for time-frequency signal analysis. His innovative ideas have been recognized with a patent that enhances the resolution of linear frequency modulated (FM) signals.
Latest Patents
Boashash's patent titled "High-resolution technique for time-frequency signal analysis" presents an apparatus and method designed to improve the resolution of linear FM signals, represented mathematically as s(t)=a(t)cos(φ(t)), where φ(t)=2.π.(s₀t+αt²). This invention involves a modified computation of the Wigner-Ville Distribution to translate or calculate an analytical signal from the received linear FM signal r(t). The invention formulates a Wigner-Ville Kernel sequence, which undergoes analysis based on advanced high-resolution estimation techniques, including least squares approximation fits or eigenvector spectral estimators like MUSIC or ESPRIT. This innovative approach provides an enhanced time-frequency representation with a resolution about an order of magnitude better than conventional discrete Fourier transform frequency analysis.
