Latest Patents
One of his latest patents is titled "Time domain multiple access broadcasting, multipoint, and conferencing." This invention discloses a method and apparatus for conducting broadcast, multipoint, and conference communications in a TDMA network at various data rates. It allows for simultaneous point-to-point communications at different data rates during time intervals within a TDMA burst. The apparatus appends a direct destination address to each point-to-point port communication for transmission over a communications link, ensuring that the intended destination port is directly addressed. Additionally, an indirect destination address is appended to each broadcast communication, with a broadcast memory provided at the receiving end to store correlated direct addresses. This innovation enables both point-to-point and broadcast-type communications to be carried out efficiently.
Another significant patent is "TDMA Intertransponder communication." This invention involves groups of stations operating in TDMA mode relative to associated frequency-separated transponder segments of a satellite repeater. The TDMA frame is partitioned into IN GROUP and CROSS GROUP intervals, allowing for multiple demand assignable burst time slots. Each node can transmit TDMA bursts in assigned slots, and the station receivers are adaptive to switch local oscillator frequencies in synchronism with transitions between the two modes. This adaptability enhances the efficiency of communication between groups.
