Non-linear spectral estimation
(Institute of Electrical and Electronics Engineers (IEEE), 1987)
Text en actes de congrés
Accés obertThis work describes the use of constraints in variational procedures for spectral analysis. It is reported how the designer in a variational approach for spectral estimation has to select a set of constraints. At the same ... -
Optical warning of bicycle riders concerning motorized vehicles closing from behind using the smartphone microphone
(Universitat Politècnica de Catalunya, 2022-02-02)
Treball Final de Grau
Accés obert
Realitzat a/amb: Technische Universität WienDeaf cyclists do not receive acoustic warnings of motor vehicles approaching from behind. This can be very dangerous because they can get startled and wobble, making them loose stability and more exposed to possible ... -
Radix-R FFT and IFFT factorizations for parallel implementation
(2009)
Article
Accés restringit per política de l'editorialTwo radix-R regular interconnection pattern families of factorizations for both the FFT and the IFFT -also known as parallel or Pease factorizations- are reformulated and presented. Number R is any power of 2 and N, the ... -
Rayleigh estimates: performing like SVD
(1988)
Text en actes de congrés
Accés obertThis paper describes the structure of the so- called Rayleigh estimates and the features they share with indirect SVD like procedures. The problem of finding procedures of high resolution in spectral estimation is faced ... -
Simulation of an OFDM system for a Wireless Battery Management System
(Universitat Politècnica de Catalunya, 2014-11-20)
Projecte/Treball Final de Carrera
Accés obert
Realitzat a/amb: Karlsruher Institut für Technologie[ANGLÈS] With the aim of innovating a new physical layer that can be used as an alternative to the standard of the Battery Management System (BMS, CAN-Bus), wireless approach proposes a new BMS communication system to ... -
Study of compression techniques for partial differential equation solvers
(Universitat Politècnica de Catalunya, 2023-07-14)
Treball Final de Grau
Accés obertPartial Differential Equations (PDEs) are widely applied in many branches of science, and solving them efficiently, from a computational point of view, is one of the cornerstones of modern computational science. The finite ... -
Transformada de fourier en processament no lineal del senyal
(Universitat Politècnica de Catalunya, 1996-12-13)
Tesi
Accés obertLa tesis presenta un modelo no recursivo de sistemas no lineales (SNLS) basado en las series de fourier, estableciendo una comparación con el modelo de volterra en términos de coste computacional y diseño. <br/><br/>Del ...
