Latest Patents
One of his latest patents is titled "Computationally efficient finite impulse response comb filtering." This invention presents a method and system designed to remove unwanted signals and their harmonics from an input signal in a computationally efficient manner. The process involves manipulating the FFT matrix to selectively zero-out rows before multiplying it with the Inverse FFT (IFFT) matrix. The resulting sparse matrix generates coefficients for a linear Finite Impulse Response (FIR) filter, effectively filtering out unwanted signals while preserving the desired signal with minimal computational effort.
Another notable patent is "Removal of matched waveform interference." This invention provides methods and systems for signal cancellation and separation in multi-signal communication environments. It utilizes a feedback-optimized multi-signal multi-stage estimator with data-aided signal parameter estimation. This approach requires minimal information about the received signals and can effectively separate desired signals from interfering ones, thereby doubling the capacity of communication systems. It is particularly useful in environments with intentional or unintentional jamming or interference.
