Abstract
A Radio Test Bed (RTB) is currently being developed for DREO under contract. The test bed is to serve as a powerful general purpose laboratory instrument for the generation and demodulation of conventional communications signals found in the tactical environment. The system will interface with the DREO Communications Jamming Simulator to allow jamming studies to be performed on various signals. The system will have the capability of generating and demodulating the following signals: AM, FM, USB, and LSB. A method has been devised to incorporate the generation and demodulation of data modulated Frequency Shift Keyed (FSK) signals into the RTB. The modulation technique involves using a baseband data signal to directly frequency modulate an RF carrier. Demodulation is achieved by using the FM demodulator of the RTB. TRUNCATED
