09 Oct 2003TL;DR: Cross-correlators as discussed by the authors are used to compute parallel short-time correlations of received signal samples and replica code sequence samples, and a means for calculating the cross-correlation values utilizing discrete-time Fourier analysis of the computed STCs.
Abstract: Signal processing architectures for direct acquisition of spread spectrum signals using long codes. Techniques are described for achieving a high of parallelism, employing code matched filter banks and other hardware sharing. In one embodiment, upper and lower sidebands are treated as two independent signals with identical spreading codes. Cross-correlators, in preferred embodiments, are comprised of a one or more banks of CMFs for computing parallel short-time correlations (STCs) of received signal samples and replica code sequence samples, and a means for calculating the cross-correlation values utilizing discrete-time Fourier analysis of the computed STCs. One or more intermediate quantizers may optionally be disposed between the bank of code matched filters and the cross-correlation calculation means for reducing word-sizes of the STCs prior to Fourier analysis. The techniques described may be used with BOC modulated signals or with any signal having at least two distinct sidebands.

TL;DR: IEEE Standard 1471 identifies sound practices to establish a framework and vocabulary for software architecture concepts to support good architectural description practices in both software intensive systems and more general systems.
Abstract: IEEE Standard 1471 identifies sound practices to establish a framework and vocabulary for software architecture concepts.In 2000, the Computer Society approved IEEE Standard 1471, which documents a consensus on good architectural description practices. Five core concepts and relationships provide the foundation for the approved IEEE 1471 version: every system has an architecture, but an architecture is not a system; an architecture and an architecture description are not the same thing; architecture standards, descriptions, and development processes can differ and be developed separately; architecture descriptions are inherently multiviewed; and separating the concept of an object's view from its specification is an effective way to write architecture description standards. IEEE 1471 focuses on both software intensive systems and more general systems, such as information systems, embedded systems, systems-of-systems, product lines, and product families in which software plays a substantial role in development, operation, or evolution.

TL;DR: This paper provides a more exact analysis of code-tracking accuracy for early-late discriminators processing conventional binary phase shift keyed signals in white noise using linear models based on a small-error assumption.
Abstract: Code-tracking accuracy, an important attribute of GPS receivers, depends both on characteristics of the signal being tracked and on the design of the receiver. A simple expression has been available to predict code-tracking accuracy for early-late processing of signals with sinc-squared spectra in white noise for an infinite
front-end bandwidth receiver. However, the literature has not indicated when this approximation holds. This paper provides a more exact analysis of code-tracking accuracy for early-late discriminators processing conven-tional binary phase shift keyed signals in white noise. New analytical expressions apply for various front-end
bandwidths, discriminator spacings, and code-tracking loop bandwidths, while using linear models based on a small-error assumption. A theoretical lower bound is also supplied, indicating inherent limits on accuracy for given conditions. While evaluation of the exact expressions requires numerical integrations, new algebraic
approximations are also provided. Numerical results compare the various expressions and approximations.

29 Jul 1990TL;DR: This paper is concerned with making precise the notion that recognizing plans is much like parsing text, and establishes a correspondence between Kautz' plan recognition formalism and existing grammatical frameworks.
Abstract: This paper is concerned with making precise the notion that recognizing plans is much like parsing text. To this end, it establishes a correspondence between Kautz' plan recognition formalism and existing grammatical frameworks. This mapping helps isolate subsets of Kautz' formalism in which plan recognition can be efficiently performed by parsing.

TL;DR: This text-mining project is unique in its integration of existing tools into a single workflow with direct application to CTD, which allowed us to measure the potential of these integrated tools to improve prioritization of journal articles for manual curation.
Abstract: Background
The Comparative Toxicogenomics Database (CTD) is a publicly available resource that promotes understanding about the etiology of environmental diseases. It provides manually curated chemical-gene/protein interactions and chemical- and gene-disease relationships from the peer-reviewed, published literature. The goals of the research reported here were to establish a baseline analysis of current CTD curation, develop a text-mining prototype from readily available open source components, and evaluate its potential value in augmenting curation efficiency and increasing data coverage.
