Abstract : Built to demonstrate the applicability of the Project West Ford channel as a high capacity digital data link, the DICON system comprises a transmitter which provides a variety of modulation signals to the West Ford RF transmitter and a receiver designed to recover the modulation signal from the output of the West Ford X-band receiving system and to measure and record the perturbations introduced by the West Ford channel. These perturbations are expected to be due principally to Doppler shift, Doppler spread and multipath delay. Since the fluctuation and multipath times may be of the same order, a noncoherent detection scheme is used. (Author)
