Power allocation for F/TDMA multiuser two-way relay networks
We consider a multiuser two-way relay network where multiple pairs of users exchange information with the assistance of a relay node, using orthogonal channels per pair. For a vari...

Fast Exponentiation Using Split Exponents
Abstract—We propose a new method to speed up discrete logarithm (DL)-based cryptosystems by considering a new variant of the DL problem, where the exponents are formed as e1 + α...

Transceiver optimization for multi-user multi-antenna two-way relay channels
In this paper, we study a multi-user multi-antenna two-way relay system, where a multi-antenna base station (BS) exchanges uplink and downlink signals with multiple users via a mu...

Continual surface-based multi-projector blending for moving objects
We introduce a general technique for blending imagery from multiple projectors on a tracked, moving, non-planar object. Our technique continuously computes visibility of pixels ov...
