Abstract:
Two modems which are candidates for the Aeronautical Satellite AEROSAT Test and Evaluation Program have been tested by the Transportation Systems Center channel simulation facility. One was a hybrid modem which can simultaneously transmit and receive both data at 1200 bps using differentially encoded phase-shift keying and voice using quadrature modulation on a single carrier. The other modem tested was the Transportation Systems Center developed digital ranging modem. Both modems were evaluated as a function of carrier to noise density with carrier to multipath ratio as a parameter. This report presents the results of these experiments.
