Title: Gregory Thomas Barnett: Innovator in OFDM Signal Processing
Introduction
Gregory Thomas Barnett is a notable inventor based in Fort Wayne, IN (US). He has made significant contributions to the field of signal processing, particularly in the area of orthogonal frequency division multiplexing (OFDM). With a total of 3 patents to his name, Barnett's work has advanced the understanding and application of OFDM technology.
Latest Patents
Barnett's latest patents include innovative techniques for equalizing and removing distributed pilot signals from OFDM signals. One of his patents focuses on the equalization of a distributed pilot OFDM signal using decision feedback. This technique involves correlating a received OFDM signal against a pilot reference to obtain a coarse channel estimate. The process allows for the removal of the distributed pilot signal to generate a coarse data signal estimate, which is then refined to produce a fine data signal estimate from which data can be recovered.
Another significant patent addresses the removal of a band-limited distributed pilot from an OFDM signal. This technique converts the received OFDM signal into a frequency domain signal, where the average magnitude of populated frequency bins is determined. This average magnitude is then used to estimate the pilot signal magnitude, allowing for the effective removal of the distributed pilot signal and yielding the OFDM data signal.
