Results of AEROSAT Channel Simulation Tests Q-M/PSK Voice/Data Modem TSC Ranging Modem

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.
