ABSTRACT:
A communication method and apparatus for providing an enhanced signal from diverse signals whereby high accuracy communication may be established between remote points, even in the presence of severe signal fading and drop outs. The information to be transmitted is provided in digital form and formatted so as to have a Barker code or sync code of adequate length to achieve the desired false alarm rate filtering, followed by the data broken up into data blocks each containing an error detection and correction code for the respective block so that accurate microsecond processing of the signals is possible. The digital signals are modulated and transmitted, ideally with a plurality of frequencies, and are received, preferably at a plurality of remote satellite receiving sites with a plurality of space, path and polarization diversity techniques. The received signals are then processed and a data output signal is constructed from the multiple signals by utilizing the data blocks for which the sync code was properly received and for which the respective error detection and correction code indicates is true data.
