Studies in graphical perception, both theoretical and experimental, provide a scientific foundation for the construction area of statistical graphics.

Consider a graph with a range of costs associated with each vertex and each edge of the graph. The range of costs for a given edge represents the possible costs charged for traversing the edge.

Novel Grassmannian beamforming techniques based on two null space broadcasting protocols are proposed for a cognitive radio network.

It is well known that availability of the channel state information (CSI) at the transmitter significantly increases the throughput of MIMO broadcast systems.

This paper introduces multidimensional generalizations of binary Reed Muller codes where the codewords are projection operators, and the corresponding subspaces are widely separated with respect to

In frequency-division duplex full-dimension massive MIMO systems, one of the main challenges is to obtain sufficiently accurate channel state information (CSI) at the transmitter to enable efficien

We report a novel wavelength selective coupler based upon grating assisted forward coupling between two, non-identical, vertically stacked InGaAsP/InP waveguides.

We report on the successful integration of grating fiber couplers, compact photonic crystal demultiplexers and efficient p-i-n photodetectors on a single bonded InP-membrane chip.

We report what is believed to be the first demonstration of optical fiber gratings written in photonic crystal fibers.

We report detailed spectral characterization of optical gratings written in different air-silica microstructured optical fibers.
