Latest Patents

One of his latest patents is titled "Toeplitz structured subspace for multiple-channel blind identification methods." This invention involves a method, a non-transitory computer-readable medium, and a system for multiple-input multiple-output blind identification. The process includes receiving an input signal, which originates as an output signal from a transmitter, at a receiver. A signal processing module is utilized to obtain the input signal from the receiver. This module employs a finite impulse response filter and matrices derived from the input signal to minimize a cost function and obtain a parameter matrix. The parameter matrix is then used to estimate the output signal by generating Toeplitz matrices.

Another significant patent is "Blind signal estimation using structured subspace technique." This system and method perform blind signal estimation for single-input multiple-output systems. The method involves receiving an observed signal, which includes the input signal and an additive noise term, through multiple receiver antennas. A data matrix is formed using the observed signals, and a singular value decomposition of this matrix is computed. The resulting parameter matrix is used to create a Toeplitz signal matrix, which aids in estimating the input signal.
