Phased Array Spread Spectrum System and Method

Abstract

A phased array spread spectrum system for maximizing signal strength of a spread-spectrum signal with multipath. A received spread-spectrum signal is delayed with respect to a phased version of the spread-spectrum signal. The delayed spread-spectrum signal is combined with the phased version of the spread-spectrum signal. A magnitude value of the combined signal is compared with a previous-magnitude value. The delay is adjusted in response to the comparison.
