Latest Patents
One of his latest patents is titled "Digital receiver instantaneous dynamic range enhancement." This invention describes a digital radio receiver system that offers improved instantaneous dynamic range response when receiving simultaneous signals. The system is designed to be cost-effective and less complex while providing a large single signal dynamic range. It utilizes a suppressed zero signal amplitude representation arrangement, which employs a selected number of signal amplitude representing digital bits instead of the entire array of digital output bits from the analog to digital converter. Additionally, the patent details a digital apparatus for selecting desired high order bits from the converter output, enhancing the receiver's performance.
Another significant patent by Graves is "Kernel function approximation and receiver." This invention presents a Fourier transformation arrangement that can be utilized in electronic warfare radio receivers. It analyzes the spectral content of brief duration incoming signals from multiple transmitters to determine their signal characteristics. The arrangement includes approximated Kernel function values positioned in various locations around a real-imaginary coordinate axis origin. The points are strategically displaced from the origin by magnitudes with real and imaginary component lengths that are powers of two. The patent also outlines guiding principles for selecting desirable approximation Kernel function locations.
