Advanced Fluid Characterization - Laboratory Information Management System

Ongoing
Breath sampling of cannabis users. I n July 2019, the National Institute of Justice awarded our team funding for a three-year project to provide the chemical foundation for industry to develop a cannabis breathalyzer. We are developing new experimental methods to enhance the clinical, thermodynamic

Advanced Security Architectures for Next Generation Wireless

Ongoing
The US Government, and the Department of Commerce in particular, has identified the development and commercialization of Open Radio Access Network (O-RAN) technologies as a strategic priority in the evolution of next-generation wireless networks and a key enabler for the US IT industry to increase

Asynchronous Cooperative Linear Dispersion Coding

Completed
The space–time block coding (STBC) techniques provide full spatial diversity in the context of collocated multiple-input–multiple-output (MIMO) systems, requiring reliable wireless communications at high rates. However, it may not always be practical to accommodate multiple antennas at the mobile
NIST engineer Kate Remley led development of new 94 gigahertz calibrated signal source and 16-antenna array operating at 83 gigahertz

5G & Beyond

Ongoing
The realization of this long-term vision requires tackling key technical challenges to allow for greater temporal, spectral, coding and spatial resource efficiency. As well, these technologies all rely on high levels of electronic device integration, yielding a radical new connectorless measurement

Composition in IoT/CPS

Completed
One approach develops a ‘CPS algebra’ based on a formal language that offers the expressive power needed to capture the observable behavior of Cyber-Physical System (CPS) components, and at the same time offers a way to express the notion of composition of CPSs. A second effort extends the in

Cooperative Diversity Routing and Transmission for Wireless Sensor Networks

Completed
In order to address the challenges of cooperation, PHY layer cooperation schemes were proposed and, to a limited extent, medium access control (MAC) layer schemes. On the network layer, the network coding techniques can be viewed as a form of cooperation as well. To the best of our knowledge, there

Cooperative vs Non-Cooperative Diversity in Space, Time and Frequency

Completed
Broadband communication plays an increasingly important role in meeting the growing demand for high-speed multimedia transmissions in our daily lives. However, when the bandwidth of a signal exceeds the coherent bandwidth of the wireless channel, the small-scale fading imposed on the signal becomes

Cooperative Single-Carrier FDMA Communications

Completed
The worldwide growth in both the number of mobile subscribers and their demand for increased rate mobile broadband services provided further impetus for the mobile telecommunication operators to improve both the capacity and the reliability of cellular networks. When communicating over broadband
