The objective of this thesis report is to make a comparative study of three scheduling algorithms for the uplink of a WCDMA system restrictive, pre-emptive and random scheduling. Performance and complexity issues are addressed. To this end, scheduling algorithms were modeled in a MATLAB environment with predefined WWW traffic model. Interesting load scenarios were defined and simulated. Results...

This paper is concerned with the distributed and centralized fusion filtering problems in sensor networked systems with random one-step delays in transmissions. The delays are described by Bernoulli variables correlated at consecutive sampling times, with different characteristics at each sensor. The measured outputs are subject to uncertainties modeled by random parameter matrices, thus provid...

The intensity statistics of random signals in the presence of Gaussian noise is obtained by considering the model of a random signal plus a random phasor sum. The additive Gaussian noise is shown to result in a Bessel transform of the probability density of signal intensity. The transformation of the intensity statistics can generally be applied to mixtures of independent random signals, one of...

|While estimating glitches or spurious transitions is challenge due to signal correlations, the random behavior of logic gate delays makes the estimation problem even more difcult. In this paper, we present statistical estimation of signal activity at the internal and output nodes of combinational and sequential CMOS logic circuits considering uncertainty of gate delays. The methodology is base...

Functional magnetic resonance imaging (fMRI) data are often analyzed using the general linear model employing a hypothesized neural model convolved with a hemodynamic response function. Mismatches between this hemodynamic model and the data can be induced by spatially varying delays or slice-timing differences. It is common practice to desensitize the analysis to such delays by incorporation of...

Markov decision processes (MDPs) may involve three types of delays. First, state information, rather than being available instantaneously, may arrive with a delay (observation delay). Second, an action may take effect at a later decision stage rather than immediately (action delay). Third, the cost induced by an action may be collected after a number of stages (cost delay). We derive two result...
