Title: Innovations of Luis R Nunez
Introduction
Luis R Nunez is an accomplished inventor based in Tucson, AZ. He holds a total of 3 patents that showcase his expertise in signal processing and equalization systems. His innovative contributions have made a significant impact in the field of digital signal processing.
Latest Patents
One of his latest patents is titled "Equalization system using general purpose filter architecture." This inventive equalization system includes first and second filters for filtering an in-phase component of a received signal using distinct sets of coefficients. Additionally, it features third and fourth filters for filtering a quadrature component of the input signal. The outputs of the first and third filters are subtracted to yield an equalized in-phase output signal, while the outputs of the second and fourth filters are added to provide an equalized quadrature output signal. The filters are implemented as finite impulse response filters, with coefficients supplied by a microprocessor. The delay elements of the filters are calculated using a mean square error algorithm, ensuring optimal performance.
Another notable invention is the "General purpose filter," which serves as a versatile signal processor. This signal processor comprises multiple filters that can be selectively interconnected to perform various digital signal processing functions. Each filter is designed to multiply input data by a coefficient and includes adders for accumulating the products. The coefficients are provided by an external processor, allowing the general purpose filter to be configured for specific functions, such as equalization, beamforming, or convolution.
