Title: The Innovations of Andrew Peter John Cartmell

Introduction

Andrew Peter John Cartmell is a notable inventor based in Palo Alto, CA. He has made significant contributions to the field of radio signal processing, holding a total of 2 patents. His work focuses on enhancing the efficiency and effectiveness of carrier tracking in radio receivers.

Latest Patents

Cartmell's latest patents include "Dynamic switching of carrier tracking loops without loss of tracking information." This innovative method involves receiving a radio signal and continuously estimating its signal-to-noise ratio (SNR). If the SNR exceeds a predetermined threshold, the system performs carrier tracking using an initial loop. If the SNR falls below this threshold, the system switches to a subsequent carrier tracking loop. Another significant patent is "Sample decimation in a GNSS receiver," which describes a method for processing Global Navigation Satellite System (GNSS) signals. This invention utilizes a wide-band Radio Frequency filter to combine signals from multiple satellite navigation systems, facilitating a reduction in the clock rate for processing.
