Latest Patents

Spencer holds 1 patent for his invention titled "System for Specific Emitter Identification." This innovative apparatus is designed to identify a specific emitter in the presence of noise and/or interference. The system includes a sensor that captures radio frequency signal data, which contains both noise and signals from at least one emitter. It features a reference estimation unit that estimates a reference signal related to the emitter's transmission. Additionally, a feature estimation unit generates estimates of features from both the reference signal and the emitter's signal. The emitter identifier then uses these estimates to identify the signal as belonging to a specific device, employing Gaussian Mixture Models and a Bayesian decision engine.
