International audience; The combination of the amplifying properties of erbium with the excellent electro-optical, acousto-optical and non-linear properties of the waveguide substrate LiNbO3 allows the development of a whole class of new waveguide de

International audience; We show that X-ray irradiation of metal salt aqueous solutions in the absence of any stabilizer leads to the synthesis of metal nanoparticles, similarly to c-ray irradiation. The chemical route is the reduction of silver metal

Multipath delay estimations using matrix pencil

Autor: N. Dharamdial, Raviraj S. Adve, R. Farha

Publikováno v: WCNC

This paper presents a technique for the recovery of time delays associated with components of a signal in a multipath communication channel. Matrix pencil is used to recover these delays from the channel frequency response. This algorithm has some ke
