Wideband Command and Control Modem (Waveform and Modem Conceptual Design Study)
Abstract
The report describes in precise terms the results of the study phase of the Wideband Command and Control Modem (WCCM) program. The study phase was devoted to the performance analysis and conceptual design of a waveform and modem which will provide a jamming-resistant command and control data link for unmanned, remote, multiple, and airborne vehicle control and position location. Direct sequence, 60 Mpps keying rate, spread-spectrum signalling using binary continuous phase shift modulation is recommended for both forward and return link communication between the ground control station (GCS) and the remotely controlled vehicles (RCVs). The forward link employs a single channel, time division multiplexed, continuous transmission for communication of command messages to the RCVs. A multichannel hybrid FDMA/TDMA return link waveform design is recommended for minimum complexity of the RCV modem and maximum flexibility in configuring the ground station for a wide range of operational requirements.
