Title: Gregory C. Copeland: Innovator in Data Transmission Technologies

Introduction

Gregory C. Copeland is a notable inventor based in Savannah, TX (US), recognized for his contributions to data transmission technologies. With a total of 12 patents to his name, Copeland has made significant advancements in the field, particularly in methods that enhance signal processing and transmission efficiency.

Latest Patents

Among his latest innovations is the patent for "Pulse cancellation crest factor reduction with a low sampling rate." This method involves detecting a signal peak of an input signal that exceeds a threshold amplitude. The process includes sampling the input signal at a frequency that is greater than the bandwidth frequency of the carrier signal but less than twice that frequency. By interpolating samples of the signal near the peak, a reconstructed peak is created, and a cancellation pulse is applied to reduce the signal peak. The output is a version of the input signal after the cancellation pulse has been applied.

Another significant patent is for "Multi-path digital pre-distortion." This apparatus features a single-band digital predistorter engine with two sample paths. The input stage separates incoming samples into first and second samples, providing magnitudes for each. The first and second sets of digital predistorters process these samples and magnitudes, ultimately producing a digital predistorted composite signal.
