Optimal sequences for CDMA under colored noise: A Schur-saddle function property
We consider direct sequence code division multiple access (DS-CDMA), modeling interference from users communicating with neighboring base stations by additive colored noise. We con...

On the optimal performance in asymmetric gaussian wireless sensor networks with fading
We study the estimation of a Gaussian source by a Gaussian wireless sensor network (WSN) where L distributed sensors transmit noisy observations of the source through a fading Gau...

Optimal beamforming in cognitive two-way relay networks
We consider a cognitive two-way relay network which consists of two transceivers (primary users) and multiple cognitive terminals. The two transceivers transmit their data toward t...
