  • Multivariable matrix spectral factorization
    Patent number: 10951919
    Abstract: A method for performing Multivariable Matrix Spectral Factorization has been developed, which allows factorization in real time high-dimensional matrices with multivariable high-order polynomial or non-rational entries. Systems implementing the method provide improved performance and capabilities in applications reducible to multivariable matrix spectral factorization.
    Type: Grant

  • Matrix spectral factorization for data compression, filtering, wireless communications, and radar systems
    Patent number: 9318232
    Abstract: A new apparatus, system, and technique for performing Matrix Spectral Factorization has been developed, which can factorize in real time high-dimensional matrices with high-order polynomial or non-rational entries. The method can be used for efficient implementation of engineering solutions to problems in Data Compression, Filtering, Wireless Communications, and Radar Systems, etc., which are computationally reducible to matrix spectral factorization.
