Title: Bruce Edward Reidenbach: Innovator in OFDM Signal Processing

Introduction

Bruce Edward Reidenbach is a notable inventor based in Albion, Indiana, with a focus on advancements in orthogonal frequency division multiplexing (OFDM) signal processing. He holds five patents that showcase his innovative techniques in equalizing and removing distributed pilot signals from OFDM signals. His work has significantly contributed to the field of telecommunications and signal processing.

Latest Patents

Reidenbach's latest patents include a technique for equalizing a distributed pilot OFDM signal with decision feedback. This method involves correlating a received OFDM signal against a pilot reference to obtain a coarse channel estimate. The received OFDM signal, which includes a distributed pilot signal and an OFDM data signal, is equalized based on this coarse channel estimate. The distributed pilot signal is then removed to generate a coarse data signal estimate. Following this, the coarse data signal estimate is subtracted from the received OFDM signal to produce a residual pilot signal. This residual pilot signal can be correlated against the pilot reference to obtain a fine channel estimate, leading to further refinement of the data signal.

Another significant patent addresses the removal of a band-limited distributed pilot from an OFDM signal. This technique converts a received OFDM signal into a frequency domain signal, which contains populated frequency bins with respective subcarrier signals. By determining the average magnitude of these populated frequency bins, Reidenbach's method estimates the pilot signal magnitude. The distributed pilot signal is then effectively removed from the frequency domain signal, yielding the OFDM data signal.
