Description:
A communication device and modulation capability were developed for the transmission of digital data or voices from point to point. This device is a fast-switching phase coherent frequency synthesizer. When this synthesizer is appropriately incorporated in a communication system it can provide interference resistance, multiple-user capability, user identification, ranging, navigation, Doppler correction, and digitized communication (voice and data). The application of this device to aircraft/airport complex and law enforcement communications is discussed.
