Title: The Innovations of Andrew McCandless
Introduction
Andrew McCandless is a notable inventor based in Baton Rouge, LA (US). He has made significant contributions to the field of communications systems, holding a total of 6 patents. His work focuses on developing advanced interference cancellation systems that enhance the quality of communication signals.
Latest Patents
One of McCandless's latest patents is titled "Remote interference cancellation for communications systems." This invention involves an interference cancellation system (ICS) designed to minimize interference from various sources. The ICS processes radio frequency (RF) signals that include signals of interest (SOI) and multiple interfering signals. An interference estimation processor (IEP) estimates the interfering signals using spatial and time diversity combined with statistical methods. The ICS then utilizes this estimated interference to cancel out the unwanted signals, allowing for clearer communication.
Another significant patent is "Interference cancellation system for cancelling interference in the optical domain." This system aims to detect signals of interest by effectively cancelling interference from received signals. It involves receiving a combined signal of interest and interference, determining a sample of the interference signal, and converting both signals to the optical domain. The interference signal is then optically phase shifted and variably attenuated, achieving over 50 dB of cancellation of the interference signal.
Career Highlights
Throughout his career, McCandless has worked with several prominent companies, including Bascom Hunter Technologies, Inc. and L-3 Communications Corporation. His experience in these organizations has contributed to his expertise in developing innovative communication technologies.
