PHOTONIC ANALOG-TO-INFORMATION RECEIVER SIGNAL PROCESSING

Abstract

Modern electronic warfare systems require increasingly larger bandwidth monitoring ability. Analog-to-information techniques increase bandwidth-monitoring capability without increasing the performance requirements placed on analog-to-digital converters. Two analog-to-information compressive sensing receiving methodologies capable of recovering signal information below the Nyquist sampling rate are considered. The designing and simulation of these receiving methodologies using photonic components in MATLAB and OptSim shows successful information recovery below the Nyquist rate. Finally, prototype receiver models were implemented using commercial off-the-shelf equipment, demonstrating rudimentary capability of recovering compressed radio frequency signal information using Mach-Zehnder interferometers as sampling devices.
