a singularity free gfdm modulation scheme with parametric Shaping Filter sampling
Vehicular Technology Conference, 2016Co-Authors: Atsushi Yoshizawa, Ryota Kimura, Ryo SawaiAbstract:A GFDM modulation scheme that circumvents the singularity issue of the GFDM transformation matrix is presented. The coefficients used for the pulse Shaping Filter are derived from the prototype Filter depending on the parity of the subsymbols. The proposed pulse Shaping Filter design makes it possible to have a non-singular transformation matrix for the arbitrary number of subsymbols and/or subcarriers in the sparse frequency-domain GFDM modulation.

On the sensitivity of third-order Volterra MVDR beamformers to interference-pulse Shaping Filter
Signal Processing, 2020Co-Authors: Jean-pierre Delmas, Pascal Chevalier, Mustapha SadokAbstract:Linear beamformers are optimal, in a mean square (MS) sense, when the signal of interest (SOI) and observations are jointly Gaussian and circular. Otherwise, optimal beamformers become non-linear with a structure depending on the unknown joint probability distribution of the SOI and observations. In this context, third-order Volterra minimum variance distortionless response (MVDR) beamformers have been proposed recently to improve the performance of linear beamformers in the presence of non-Gaussian and potentially non-circular interference, omnipresent in practical situations. High performance gains have been obtained for binary phase shift keying (BPSK) and quadrature phase shift keying (QPSK) interference having a square pulse Shaping Filter in particular. However in practice, for spectral efficiency reasons, most of signals use non-square pulse Shaping Filters, such as square root raised cosine Filter. It is then important to analyze the sensitivity of third-order MVDR beamformers to interference pulse Shaping Filter, which is the purpose of this paper.
