System for Extracting Venous Pulsation and Respiratory Information from Photoplethysmographs

The University of Texas at Dallas presents a technique that addresses the inaccuracy of skin-mounted photoplethysmographic (PPG) biosensor measurements by separating the arterial and venous signals - enabling extraction of other medically-relevant features, including: respiration rate, heart rate, and SpO2. The effective removal of various motion artifacts...

Accurate and Motion-Tolerant Sensing of Arterial and Venous Pulsation for Wearable Photoplethysmographic (PPG) Biosensors

The University of Texas at Dallas presents a real-time, adaptive technique that provides robust signal enhancement against motion artifact for wearable photoplethysmographic (PPG) systems, enabling the reliable extraction of heart rate and oxygen saturation. Despite the benefits of using PPG biosensors, most of the useful information they capture...

Coherence Diversity in Frequency and Time

The University of Texas at Dallas is seeking companies interested in commercializing a diversity scheme for wireless networks, called coherence diversity, which provides a novel source of gain that is distinct from other kinds of diversity. As individual links in a wireless network often experience unequal fading coherence times and coherence bandwidths...

Spectrum-Agile Massive MIMO System and Capacity Adaptation Between Uplink and Downlink

Massive MIMO is a potential candidate for next-generation wireless communication, such as for 5G. Massive MIMO uses a large number of base station (BS) antennas to potentially allow for orders of magnitude improvement in spectral and energy efficiency. Existing Massive MIMO literature views that such technology with large number of beams (large number...
