Title: The Innovative Contributions of Dean McArthur
Introduction
Dean McArthur is a notable inventor based in Burlington, CA. He has made significant contributions to the field of communication technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and effectiveness of communication systems.
Latest Patents
One of McArthur's latest patents is titled "Multi-channel demodulation with blind digital beamforming." This invention provides a system and method for receiving communication signals. The method involves receiving multiple communication signals, each comprising one or more source signals. These signals are multiplexed into a single multiplexed signal, which is then converted into a baseband signal. The baseband signal is sampled to produce a digital multiplexed signal, and the samples are interpolated to generate respective interpolated digital signals. A blind signal separation operation is then applied to separate each of the source signals.
Another significant patent is the "Noise suppression circuit for a wireless device." This adaptive noise suppression system includes an input A/D converter, an analyzer, a filter, and an output D/A converter. The analyzer features both feed-forward and feedback signal paths that allow it to compute a filtering coefficient, which is input to the filter. The system processes signals to preserve speech-like signals while suppressing incoherent noise signals. The noise suppression filter estimator outputs a filtering coefficient signal to the filter for effective noise reduction.
