Latest Patents
One of his latest patents is titled "System and method for multiple access short message communications." This invention describes a communications system that utilizes frequency division multiple access (FDMA), code division multiple access (CDMA), and time division multiple access (TDMA) techniques. It aims to provide efficient use of frequency spectrum while supporting a large number of transmitters and users. The system allows many users to share a common frequency band, transmitting their respective message bursts at different and specific times via a TDMA technique. To facilitate synchronization, each transmitter is synchronized to a common timing reference, which simplifies the synchronization process between transmitters and receivers. The TDMA messages are transmitted using a spread spectrum technique, enhancing the reliability of communication.
Another notable patent is "Apparatus for despreading and demodulating a burst CDMA signal." This invention focuses on an asynchronous communications receiver that rapidly despreads and demodulates a short, low duty cycle CDMA burst signal. The receiver includes a multichannel despreader that generates multiple despread signals corresponding to timing offsets of a spreading code. These signals are processed by a plurality of demodulators, which generate soft decisions proportional to the quality of the received signal. The system effectively combines these signals to extract the actual received digital message.
