AI-generated Abstract
The modern communications environment is becoming an increasingly crowded place, resulting in rapidly increasing demands on current technology. In this thesis, we describe the unique advantages of our receiver concept to allow for frequency re-use as well as cell sectoring methods to increase the overall data capacity bandwidth. Primarily, the use of a distrusted aperture array enables high resolution imaging, limited only by the diffraction efficiency set at the antenna array. Thus, angle-of-arrival (AoA) capabilities help deduce the position of each signal and the data it contains. Unlike IR or visible wavelengths, millimeter waves have the unique ability to penetrate dust, smoke, cloud coverage, and thin fabrics such as clothing. As such, millimeter wave receivers have the capability of achieving high signal-to-noise ratios (SNR) in obscured environments compared to their counterparts. This optically addressed communication receiver offers vast advantages over current communication receiver architectures in place today. This approach has the potential to operate as the next generation communication receiver for 5G wireless. In addition, this receiver concept appeals to many security and defense applications requiring secure communications and unwanted signal avoidance.
