Title: Innovations by Roger A McDanell

Introduction

Roger A McDanell is an accomplished inventor based in Carmel, IN (US). He has made significant contributions to the field of satellite receiver technology, holding two patents that enhance the performance and reliability of these systems. His work is characterized by innovative methods that address critical challenges in signal processing.

Latest Patents

One of McDanell's latest patents is titled "Methods to extend the frequency lock range of a received RF signal using a preamble-based frequency estimate." This method involves analyzing data information from a preamble associated with a received satellite RF signal. It determines an estimated frequency value based on this analysis, which is then compared to a predetermined threshold value. If the estimated frequency exceeds this threshold, it is used to control the tracking mode electronic circuitry in the satellite receiver, thereby achieving frequency lock on the received signal.

Another notable patent is "Satellite receiver performance enhancements." This patent presents several enhancements, including the use of correlation values to block satellite signal data transmission when the correlation is below a predetermined threshold. It also incorporates Reed-Solomon codeword error checking to prevent erroneous data from being accepted. Additionally, it involves storing symbol timing and frequency data during strong signal conditions for use during weak signal conditions, as well as mitigating DC offset noise in receivers with zero-IF tuners.
