Latest Patents

One of her latest patents is titled "Equalization system using general purpose filter architecture." This inventive equalization system includes first and second filters that filter 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 produce an equalized quadrature output signal. The filters are designed as finite impulse response filters, with coefficients provided by a microprocessor. The system employs a mean square error algorithm to calculate the delay elements of the filters, ensuring optimal performance.

Another significant 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 supplied by an external processor, allowing the general purpose filter to be configured for specific functions, such as equalization, beamforming, or convolution.
