RF Channel Simulator for Wireless Communications
Project Award Date: 04-25-1997
This research involves the design, implementation, and testing of a hardware-based, wireless communications channel simulator. The purpose of the simulator is to provide a laboratory test instrument of revaluating UHF radios. The simulator allows ith radios to be tested in a controlled RF envronment that can be configured under operator control to approximate closely the propagatrion conditions found in the confines of a typical hospital. This environment includes flat fading, coherent interference, background noise, and impulsive noise. In order to provide realistic performance the behavior of the simulator is based on actual channel measurements. These measurements have been incorporated into a software tool (SircimPlus) which generates the behavior files based on parameters which are input to this program by the operator. Our task is to verify the preliminary design of a channel simulator, assemble the necessary RF components, fabricate any external circuitry that may be required, program the user interface and any necessary software friver, and integrate the system into an operational unit.
