Abstract: A spread spectrum communications system adapted to receive simultaneous signals from multiple transmitters, separates frequency error and equalizes and decodes continuous streams of data sets from a plurality of matched filters with frequency correction and which sorts through data and successfully decodes data bits.

Abstract: A method and system for determining the location of a mobile transmitting device that uses three dimensional location coordinates to triangulate the location using a time difference of arrival method, with diminishing errors, error correction and which takes advantage of global positioning systems without the requirement of highly accurate clocks in the mobile transmitting device and the base stations.
Abstract: A spread spectrum communications system using long, scalable PN sequences to achieve variable communication rates using a low-complexity and scalable matched filter architecture to provide a large processing gain, robust recovery of multiple devices in long reach, high ambient-noise environments.
