Multipath Channel Simulation and Modem Evaluation Program.

Abstract

The Department of Transportation, Transportation Systems Center has developed a laboratory communications test facility. To evaluate in a laboratory controlled simulated environment, alternative modulation techniques having potential application in aeronautical and maritime satellite communications and surveillance systems. The main feature of the communication test facility is the hardware for simulating, by means of laboratory equipment, the narrowband (50 KHz) AEROSAT satellite-to-aircraft propagation channel. The simulator also simulates the maritime satellite-to-ship propagation channel and is expandable to wideband (10 MHz) systems; e.g., future CONUS ATC Systems. The simulator includes provisions for duplicating multipath phenomena over the satellite links and includes provisions for adjustment and programming of channel parameters covering a wide range of environmental conditions.
