Abstract
A spread-spectrum system and method for providing high capacity communications through multipath compensation. A multipath processor including a first plurality of correlators, a second plurality of correlators, a first adder, a second adder, and a selector device or a combiner device is provided for tracking a spread-spectrum signal arriving in a plurality of groups. The first plurality of correlators despreads a first group of spread-spectrum signals as a first group of despread signals which are added by the first adder to generate a first combined-despread signal. The second plurality of correlators despreads a second group of spread-spectrum signals as a second group of despread signals which are added by the second adder to generate a second combined-despread signal. The selector device selects either the first or the second combined-despread signal and outputs the selected signal. Alternatively, the combiner device combines the first and the second combined-despread signals and outputs the combined signal.
