Bidirectional estimation on the number line in kindergarteners: the effect of the familiarity with numbers
(2015)
In recent years, mapping tasks have been used to explain development of symbolic and non-symbolic numerical
associations. The bidirectional mapping hypothesis (Castronovo & Seron, 2007) postulates that transcoding ...
Tensor space-time (TST) coding for MIMO wireless communication systems

Endpoint Estimates of Commutators of Singular Integrals vs. Conditions on the Symbol
(Birkhauser Boston Inc, 2020-01)
Endpoint estimates of commutators Tb of singular integrals T, are studied over general spaces that include, in particular, BMO and Lipschitz spaces. We also characterize the conditions of the symbol b in order to obtain ...
Dispersive estimates for rational symbols and local well-posedness of the nonzero energy NV equation. II
(Academic Press INC Elsevier Science, 2018)
We continue our study on the Cauchy problem for the two-dimensional Novikov-Veselov (NV) equation, integrable via the inverse scattering transform for the two dimensional Schrodinger operator at a fixed energy parameter. ...
Spread spectrum orthogonalization of superimposed training signals in OFDM systems
(Institute of Electrical and Electronics Engineers Inc., 2017-10)
In this paper, we propose a novel Superimposed Training (ST) technique for Orthogonal Frequency Division Multiplexing (OFDM) systems, where data and training signals are divided in orthogonal code domains in order to ...
Lattice constellations and codes from quadratic number fields
(2001-05-01)
We propose new classes of linear codes over integer rings of quadratic extensions of Q, the field of rational numbers. The codes are considered with respect to a Mannheim metric, which is a Manhattan metric modulo a ...
