Matthew Carrick 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).

  • Method for jointly adapting an OFDM waveform and the demodulator for interference mitigation and harsh channels
    Patent number: 10200138
    Abstract: The present invention provides a method and system for a processing multicarrier signal to create a spectral correlation across multiple antennas. The system includes at least one transmitter adapted to create a plurality of symbols, each symbol representing one or more bits from a plurality of bitstreams. The transmitter creates a plurality of repetition patterns, each pattern containing a copy of the symbols and each repetition pattern comprising a combination of symbols that varies in time, frequency and space. The repetition patterns are transmitted over and received by one or more separate antennas where a receiver demodulates the repetition patterns and linearly combines each repeated symbols across time, frequency and space to estimate said transmitted symbol.
