Title: The Innovative Mind of Chris Pagnanelli

Introduction

Chris Pagnanelli is a notable inventor based in Huntington Beach, California. He has made significant contributions to the field of signal processing, holding a total of seven patents. His work focuses on developing advanced systems for reducing interference in communication signals.

Latest Patents

One of his latest patents is titled "Frequency Domain Echo and Next Cancellation." This invention discloses a cancellation system designed for processing incoming and outgoing signals in a transform domain. It creates a cancellation signal aimed at reducing or removing unwanted interference. The data is organized based on Good-Thomas indexing into a two-dimensional array in a buffer. The columns of data undergo a Winograd small transform, while the rows undergo a Cooley-Tukey operation to complete the transformation into the frequency domain. The transformed data is then scaled using multipliers to generate a cancellation signal. Inverse processing is performed to return the cancellation signal to the time domain, achieving effective interference cancellation.

Another significant patent is the "Method and Apparatus for Reducing Transmitter AC-Coupling Droop." This invention provides a droop compensator within a transmitter and receiver system. The compensator is designed to improve power transfer to the channel in response to reduced transition densities without affecting power transfer during high transition density periods. It creates an impedance mismatch between the matching circuit and driver in relation to the line impedance. The droop compensator can include both passive and active elements, such as capacitors, inductors, transistors, or power control modules.
