Abstract: A schema for a document generation system and a method of generating a document. In one embodiment the schema includes a template root element; a template information element; a data table element; and an instances element. In another embodiment, the method includes generating one or more composition elements. Each composition element is configurable to include a level, and is capable of manifesting itself as a document page, a page-level overlay, or an instance-level, conditional overlay. The method also includes laying composition elements on a rendering surface such that elements with a high level replace elements with a low level; wherein each composition element includes pre-authored formal content.

Abstract: A system that may be used to generate documents and for broader uses such as assembling computer-processable components into computer-processable end products. In one form, the system is a document generation system having an assembly facility configured to be coupled to an origination platform; a knowledge base configured to be coupled to the assembly facility and to store objects in an object-relational hierarchy; and a content management system configured to be coupled to the knowledge base, where the content management system is configured to include an object and a rule. The system may be configured to interact with a knowledge base to create a first set of end products, each end product containing an object; apply precedence to the first set of end products; extract rules from the knowledge base; and assemble a second set of documents based upon applying precedence and rules.

Abstract: A data structure generation system. The system includes a knowledge base configured to store data structure components as objects in an object-relational hierarchy. Each object is configured to have a precedence, to include one or more rules, and to include content. The knowledge base may be coupled to a data structure assembly facility configured to retrieve one or more cross-referenced data structure components from a database. The one or more data structure components are configured to have a precedence level, and may be processed in a processor to generate a tree having a root node. The tree may be processed beginning at the root node, and objects of low precedence may be overidden with objects of high precedence.

Abstract: A method and system for modulating and detecting high datarate symbol communications provides superior performance in channels having a fixed spectral efficiency. A quadrature amplitude modulation (QAM) constellation and an optimized mapping are employed to encode/detect a communications signal and error correction is provided using high speed forward error correction techniques. A log likelihood detection scheme and/or a novel phase detector may be employed to further enhance performance.

Abstract: A digital Intermediate Frequency (IF) processing block including a decimation filter having Finite Impulse Response (FIR) decimation stages provides improved performance over a Hogenauer decimating filter. The filter comprises multiple integrator stages followed by multiple FIR decimating stages. The zeros of the filter are tunable by adjusting the integer coefficients of the FIR stages providing tunability of the cut-off response, as opposed to the fixed sinc response of the Hogenauer filter. As a result, the number of required stages for a particular steepness is reduced, dramatically reducing the amount of digital circuitry required to implement a particular filter design. The improved filter is especially suitable for use in digital IF stages in receivers, and for code-based applications where selectable decimation rate is desired and a fast multiply is not available.
