Joint bandwidth and power allocation in cognitive radio networks under fading channels
A problem of joint optimal bandwidth and power allocation in cognitive networks under fading channels is considered. It is assumed that multiple secondary users (SUs) share the sp...

Mixed-integer linear programming framework for max-min power control with single-stage interference cancellation
We consider a wireless network comprising a number of mutuallyinterfering links. We study the transmit power control problem that determines the egalitarian signal-to-interference...

Transceiver design with vector perturbation technique and iterative power loading
— In this paper we consider the optimization of transceivers which use the nonlinear vector perturbation technique at the transmitter. Since the perturbation vector can be almost...

A 2D representation for analysis and coding of power quality events
In this work, we demonstrate examples about uses of practical image processing techniques over a new interpretation of power quality event data. Power quality event data are 1D da...

Fast noise tracking based on recursive smoothing of MMSE noise power estimates
We consider estimation of the noise spectral variance from speech signals contaminated by highly nonstationary noise sources. In each time frame, for each frequency bin, the noise...
