Professor Anthony Ephremides (ECE/ISR), Gigla Janashia, former postdoctoral researcher and visiting scholar Lasha Ephremidze, and Edem Lagvilava were issued U.S. Patent No. 9,318,232 on April 19, 2016.

The patent is for Matrix spectral factorization for data compression, filtering, wireless communications, and radar systems. The invention is a new apparatus, system, and technique for performing matrix spectral factorization. The method can factorize in real time high-dimensional matrices with high-order polynomial or non-rational entries. It can be used for efficient implementation of engineering solutions to problems in data compression, filtering, wireless communications, radar systems, and so on, which are computationally reducible to matrix spectral factorization.
