On Capture in Random-Access Systems
2006 IEEE International Symposium on Information Theory, 2006Under power-based capture, a transmission is correctly decoded at the destination, even in the presence of other transmissions, if the received signal-to-interference-plus-noise ratio (SINR) exceeds a threshold b ges 0. Studies on capture are often limited to the case b ges 1.

Distributed Antenna Systems with Randomness
IEEE Transactions on Wireless Communications, 2008In a cellular distributed antenna system (DAS), distributed antenna elements (AEs) are connected to the base station via an offline dedicated link, e.g. fiber optics or line-of-sight RF. Distributed antennas have been recently shown to provide considerable gains in coverage and capacity, at much lower cost than decreasing cell size.

Partial realization of random systems
Automatica, 1972Abstract An algorithm is presented for the recursive determination of certain lumped linear models that when driven by a white-noise sequence yield outputs whose covariances match increasing sections of a given covariance sequence.

On the Stability of Random Systems and the Stabilization of Deterministic Systems with Random Noise
The Journal of the Acoustical Society of America, 1960A general theory of mean square stability of random linear systems is developed when several system parameters vary as white noise stochastic processes. It is found that stability in mean square is determined from the character of the roots of a determinantal equation involving the Fourier transforms of double products of the weighting functions of the

The Transient Spectrum of a Random System
IEEE Transactions on Signal Processing, 2010The frequency spectrum is a fundamental quantity for the analysis and design of a system. When a system is turned on or off, the frequency spectrum of its output changes with time. We define the transient spectrum as the time-frequency spectrum of the system output during the transient phase.

Controlling the Dynamics of a Random System
1992Random systems, dynamical systems and control systems can all be described as flows on (finite or infinite dimensional) spaces, which allows for the use of unified concepts in the analysis of their qualitative long term behavior. In particular there is a close connection between the attractors of an undisturbed system, the stationary and ergodic ...

Linearization of Random Dynamical Systems
1995At the end of the last century the French mathematician Henri Poincare laid the foundation for what we call nowadays the qualitative theory of ordinary differential equations. Roughly speaking, this theory is devoted to studying how the qualitative behavior (e.g.
