Position and velocity tracking in mobile networks using particle and Kalman filtering with comparison
(2008)This paper presents several methods based on signal strength and wave scattering models for tracking a user. The received-signal level method is first used in combination with maximum likelihood (ML) estimation and ...

A state-space approach in modeling multipath fading channels via stochastic differential equations
(2001)The analysis, modeling and simulation of time-varying multipath wireless fading channels is usually done through input-output descriptions of the channel. In this paper, we introduce the concept of the state of the channel ...

Statistical analysis of the received signal over multipath fading channels via generalization of shot-noise
(2001)This paper is a continuation of the companion paper [1], in which multipath fading channels (MFC) are formulated as generalizations of the shot-noise analysis in investigating the statistical properties of wireless channels ...

Stochastic models for short-term multipath fading channels: chi-square and Ornstein-Uhlenbeck processes
(IEEE, 1999)This paper discusses the use of stochastic differential equations to model signal envelope variations over areas, which are subject to short-term fading effects. The short-term fading effects are modeled using Ornstein-Uhlenbeck ...

Stochastic power control for wireless networks via SDEs: Probabilistic QoS measures
(2005)The power control of wireless networks is formulated using a stochastic optimal control framework, in which the evolution of the channel is described by stochastic differential equations (SDEs). The latter rapture the ...
