Augmenting Wireless Security Using Zero-Forcing Beamforming
We present the design and experimental evaluation of Simultaneous TRansmissions with Orthogonally Blinded Eavesdroppers (STROBE). STROBE is a cross-layer approach that exploits the multi-stream capabilities of existing ...
Directional Antenna Diversity for Mobile Devices: Characterizations and Solutions
We report a first-of-its-kind realization of directional transmission for smartphone-like mobile devices using multiple passive directional antennas, supported by only one RF chain. The key is a multi-antenna system (MiDAS) ...
Approximate logic circuits: Theory and applications
CMOS technology scaling, the process of shrinking transistor dimensions based on Moore's law, has been the thrust behind increasingly powerful integrated circuits for over half a century. As dimensions are scaled to few ...
Limits and Capabilities of Cooperative Diversity: A Network and Protocol Perspective
Physical-layer cooperation has been demonstrated to vastly improve wireless link reliability and end-to-end throughput by exploiting spatial diversity. Nevertheless, its performance in operational networking environments ...
Cooperative Partial Detection for MIMO Relay Networks
Cooperative communication has recently re-emerged as a possible paradigm shift to realize the promises of the ever increasing wireless communication market; however, there have been few, if any, studies to translate ...
Optical spectroscopy and imaging systems for gynecological cancers: from Ultraviolet-C (UVC) to the Mid-infrared
Optical spectroscopy and imaging has proving to be of diagnostic relevance in many organ sites. We use fluorescence and FTIR spectroscopy to study gynecological organ sites and develop classification algorithms for cancer ...
