Patents by Inventor Theodore Mark Kellum

Theodore Mark Kellum has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • THREE-DIMENSIONAL WAFER-STACKED OPTICAL AND RADIO FREQUENCY PHASED ARRAY TRANSCEIVER SYSTEM
    Publication number: 20220239383
    Abstract: A communication system includes an antenna assembly. The antenna assembly includes an optical communication layer including a plurality of electro-optical (EO) antennas for communicating via an EO signal and a radio-frequency communication layer including a plurality of radio frequency (RF) antennas for communicating via an RF signal. A processor operates the antenna assembly to communicate via one or both of the EO signal and the RF signal.

  • System and method of digital signal processing
    Patent number: 10720960
    Abstract: A system and method for transmitting a digital signal comprising includes a random number generator for generating a pseudorandom code. A scheduler stores a plurality of signal sequences each matching a set of bandwidth-time products and center frequencies with a stored code. The scheduler selects a signal sequence by matching the pseudorandom code with one of the stored codes. The scheduler selects a bandwidth-time product and center frequency based on the selected signal sequence. A baseband processing unit generates the digital signal based on a selected bandwidth-time product and center frequency. A front end processing and beamforming unit broadcasts the digital signal.
