Abstract: A method of processing a radio frequency signal includes: receiving the radio frequency signal at an antenna of a receiver device; processing, by a radio frequency front-end device, the radio frequency signal; converting, by an analog-to-digital converter, the analog signal to a digital signal; receiving, by a neural network, the digital signal; and processing, by the neural network, the digital signal to produce an output.

Abstract: Exemplary embodiments of the present disclosure are directed to a machine learning-based receiver that operates on the basis of a wide-band RF front-end. The RF front-end outputs clean IQ data to a SPectrum-Analysis-Isolation-Synthesis (SPAIS) system in order to collect analytics of signals present within the monitored band of frequencies, including signal center frequencies, bandwidth and power. The SPAIS system pre-processes the captured wideband IQ data in order to locate frequency bands with signal energy, isolate and synthesize the located frequency bands in corresponding IQ data for individual processing by a neural network with high classification accuracy.
