Title: Innovations by Steven Andersen in Cross-Polarization Equalization
Introduction
Steven Andersen is a notable inventor based in San Jose, CA, who has made significant contributions to the field of signal processing. He holds 2 patents that focus on innovative solutions for cancelling interfering signals in communication systems. His work is particularly relevant in enhancing the performance of receivers in environments with low cross-polarization isolation.
Latest Patents
One of Andersen's latest patents is the "Adaptive Cross-Polarization Equalizer." This invention employs a receiver to cancel an interfering signal by utilizing a simple and cost-effective cross-polarization interference cancellation system. The equalizer determines the magnitude of the interfering signal using an error signal generated in an adaptive baseband equalizer. It inputs a cancelling signal to the co-polarized channel until the power in the error signal is minimized. This technology allows for the transmission of two unique signals within the same frequency allocation on orthogonal polarizations, even when the modulations and data rates differ.
Another significant patent by Andersen is the "Residual Carrier Adaptive Cross-Polarization Equalizer." Similar to his previous invention, this equalizer is designed to cancel interfering signals due to low cross-polarization isolation. It uses an error signal from a residual carrier detector to determine the magnitude of the interfering signal. The cancellation process occurs at RF, prior to dispersive microwave elements, ensuring effective signal processing.
