Latest Patents

One of his latest patents is titled "Reconfigurable protocols and architectures for wireless networks." This invention provides a reconfigurable architecture for wireless digital data and voice communications, allowing user wireless communication units to serve as relay stations. This enables users within range of each other to access local and wider-area networks through a multihop process. The architecture supports dynamic protocol 'preferencing' and facilitates easy upgrades to future wireless protocol standards. Additionally, it promotes power-efficient communication by utilizing multihop radio communication at the local level and high-speed point-to-point links at the global level.

Another significant patent by Gray is the "Method and apparatus for parallel signal processing." This invention outlines a method for conducting signal processing operations, including convolution and filtering, where each parallel stream processes signals at a lower rate than the signal data rate itself. This approach allows for the use of devices with lower signal processing rates in parallel processing paths, thus avoiding many challenges associated with high data rate signal processing. The invention effectively converts signals from the time domain to the frequency domain, leveraging the associative and communicative properties of data processing.
