Funded Research Projects (supervising graduate & undergraduate students): -Innovated a Manchester code delta detector (patented) - a method that can reduce half of the power in data transferring. -Designed digital filters to have removed video artifacts (the “salt & pepper” noise) without losing the sharpness of the picture. -Physiological/musical noise reduction with the useful biological information preserved by Wavelet -- a method overcomes the drawback of conventional filtering. -Visual friendly display of healthcare monitoring signals made by P-Z plot (collaboration with Mayo Clinic), and its sensitivity are calculated. -Simulated and compared ultra-wide band (UWB) radio in different modulation schemes. -Prototyped the wireless PDA data transfer security system. -RFID identical tags detection and anti-collision ALOHA protocol simulation. -Modeled the cardiovascular human heart by an adjustable order linear system. -Investigated the energy patterns of blood pressure waveforms. -Detecting cardiac sounds of fetus in the noisy environment by adaptive filter.
