Terrestrial laser scanning instruments are coming more and more into operation. Up to now vendors of laser scanners
mainly use manual or semi-automated registration techniques combined with artiʂ...
Iterative water-filling for Gaussian vector multiple access channels
channel capacity convex optimization Gaussian channels multiuser channels multiple-access channels multipleaccess communications multiple-antenna systems optimization methods power control water-filling
2015/8/11
We develop an efficient iterative water-filling algorithm to find an optimal transmit spectrum for maximum sum capacity in a Gaussian multiple access channel with vector inputs and a vector output. Th...

2013/7/3
The properties of a pair of vortices embedded in a Gaussian beam focused by a high numerical-aperture are studied on the basis of vector Debye integral. The vortices move and rotate in the vicinity of...
Polarisation singularities of non-paraxial Gaussian vortex beams diffracted by an annular aperture
polarisation singularities non-paraxial annular aperture C-points
2013/7/3
Based on the vectorial Rayleigh–Sommerfeld diffraction integrals, the propagation expressions for non-paraxial Gaussian vortex beams diffracted by an annular aperture are derived, and are used to anal...
