The Talbot interferometer has been shown earlier to act as an optical tapped delay-line in the time domain. The interferometer is based on the self-imaging effect. It consists of two gratings separated by a multiple of the self-imaging distance. Here, we determine its temporal behaviour experimentally. First, the impulse response is measured directly in the time domain by means of femtosecond p...

We study the Godard/CMA error surface in adapting the impulse response coefficients of a finite-length, tapped-delay-line filter to equalize a white, zero-mean, binary (21) source that suffers IS1 due to a linear channel. Our results arise primarily from examination of the expressions for the gradient and the Hessian in the baud-spaced equalizer parameter space of the cost-function in this part...

Distributed real-time control applications consist of sets of tasks that interact with the physical world through sensors and actuators and are executed on a dispersed set of locations that are interconnected by a communication subsystem. Timeliness and safety requirements of the application demand deterministic execution of tasks and predictive communication. Deterministic and predictable syst...

This paper presents an on-line coupled filter extension to the method of Tsatsanis et al. [1] for identification of randomly time-varying linear channels. The channel is modelled as a tapped-delay line filter, with tap coefficients described by an unknown auto-regressive (AR) process. We propose an augmented-state Kalman filter for tracking the channel taps and estimating the mean channel respo...

Spread-spectrum signals with long signature sequences are considered in this papez Particularly, a linear receiver proposed in [1] and [2] for direct-sequence spreadspectrum multiple access systems is extended to its iterative form. This extension is most applicable in situations with high processing gain, where it is necessary at times to use a large number of correlators to acquire the PN seq...

The paper first presents the integration options of what we call the Timing Description Language (TDL) with MathWorks' Simulink tools. Based on the paradigm of logical execution time (LET) as introduced by Giotto [2], TDL enhances Giotto towards a component architecture for real-time control applications [9]. The challenge is to provide appropriate visual and interactive modeling capabilities s...

The outage probability of a forward link DSCDMA cellular system with fast transmit power control (TPC) based on signal-to-interference ratio (SIR) is investigated. The expression for SIR at the output of RAKE receiver is developed, and the outage probability is evaluated by using Monte Carlo simulation. We consider two kinds of channel models: random delay resolvable path model and tapped delay...

This paper presents a time delay neural network (TDNN) model designed for the prediction of nitrogen oxides (NO x) and carbon monoxide (CO) emissions from a fossil fuel power plant. NO x and CO emissions of the plant are determined as a function of other related time-series such as air ow rates and oxygen levels that are measured during the system operation. Correlation analysis is performed on...
