Abstract:

Unmanned Aerial Vehicle (UAV) command and control links are highly sensitive to intentional interference and signal distortion, which may lead to performance degradation or loss of control. This paper presents a simulation-based study of UAV command signal degradation using Double Sideband Suppressed Carrier (SC-DSB) modulation implemented in a LabVIEW environment. A mathematical model of the SC-DSB signal is developed and integrated into a configurable simulation framework that allows controlled variation of key parameters, including modulation index, interference power, carrier frequency, and noise level. The proposed model evaluates the impact of SC-DSB signal injection on command signal integrity by analyzing spectral characteristics, signal-to-noise ratio (SNR), error metrics, and time–frequency behavior. Simulation results demonstrate that carrier suppression combined with controlled sideband energy distribution significantly affects demodulation stability and command signal reliability under interference conditions. The developed LabVIEW framework provides a flexible tool for studying UAV control link vulnerabilities and can support further research on electronic countermeasure strategies and resilient communication system design.
