Title: The Innovations of Daniel Davidson MacFarlane Shearer, III
Introduction
Daniel Davidson MacFarlane Shearer, III is an accomplished inventor based in Scottsdale, AZ. He holds a total of 3 patents that showcase his expertise in the field of communications technology. His innovative work has contributed significantly to advancements in carrier tracking circuits.
Latest Patents
One of his latest patents is titled "Carrier tracking circuit and method including dual numerically controlled oscillators and feedforward phase correction coefficient." This invention features a carrier tracking circuit that includes a first phase adjustment circuit coupled to an input of a delay element and a second phase adjustment circuit coupled to an output of the delay element. A phase correction circuit is also included, which generates a phase adjustment value based on a data symbol output from the delay element. The design incorporates a double phase correction circuit to prevent the double application of the same phase adjustment value to a symbol by both phase adjustment circuits. This carrier tracking circuit is particularly useful in Orthogonal Frequency Division Multiplexing (OFDM) communications systems, where each data symbol is an OFDM symbol, and the delay element functions as a Fast Fourier Transform (FFT). Additionally, the circuit may include a feedforward circuit for correcting the phase error of a given data symbol using a phase error generated from that symbol.
Career Highlights
Throughout his career, Daniel has worked with notable companies such as Globespan Virata Corporation and Conexant, Inc. His experience in these organizations has allowed him to refine his skills and contribute to significant technological advancements.
Collaborations
Daniel has collaborated with various professionals in the field, including his coworker Michael J. Seals. Their joint efforts have further propelled innovation in their respective projects.
