    摘要： A wireless spread spectrum communication platform for processing a communication signal is disclosed herein. The wireless communication platform includes a first computing element, a second computing element, and a reconfigurable interconnect. The first computing element is coupled to the second computing element via the reconfigurable interconnect. A design configuration of the first computing element is heterogeneous with respect to a design configuration of the second computing element. The reconfigurable interconnect has an uncommitted architecture, thereby allowing it to be configured by an outside source to couple portions of the first reconfigurable interconnect with portions of the second reconfigurable interconnect in a variety of combinations. The first computing element, the second computing element, and the reconfigurable interconnect operable to perform discrete functions suitable for processing of the communication signal.

    摘要： An embodiment of the invention described in the specification and drawings is an apparatus and method of generating a phase-shifted maximum length pseudo-random noise (PN) sequence without resorting to complicated counters and clocking schemes. The apparatus includes a linear feedback shift register (LFSR) that has N stages and the ability to generate a first PN sequence at an output of its last stage. The LFSR is coupled to a first mask circuit and a second mask circuit for generating a second PN sequence and a third PN sequence. The apparatus further includes logic for selectively outputting bits from the second and third PN sequences to form a fourth PN sequence, which has a phase shift relative to the first PN sequence.

    摘要： A new approach to aggregating a plurality of information exchange requirements (IERs) into a common schema is disclosed. An aggregation method includes the broad steps of tabulating the plurality of IERs into an ordered format, identifying a plurality of commonalities in the ordered format, and formulating the common schema from the ordered format. The common schema includes a data structure having a number of content-based attributes fields, wherein each of the content-based attributes fields corresponds to one of the context-neutral commonalities in the ordered format.
