Abstract
A method and apparatus for reducing deep fading of signals in satellite-based communications systems employing terrestrial repeater stations by shifting the phase of the signals transmitted from each terrestrial repeater station by a different amount so that the signals are transmitted from each terrestrial repeater station and received at a receiver at different phases, thereby effectuating time diversity in such signals to reduce deep fading of the signals. The method and apparatus can be used in CDMA and OFDM systems.
