Wireless Communication and Signal Processing Group
Dr. Huseyin Arslan
Website

Wireless Communications and Signal Processing (WCSP) Group, formed by Dr. Arslan in 2002, has been expanding its knowledge in wireless communications/networks and digital baseband signal processing areas to take the forefront lines in the formation of future technologies. With diverse offering of courses introducing the knowledge from fundamentals to the state-of-the-art developments in the field, our aim is to develop highly competitive undergraduate/graduate students who are well educated in multiple areas of wireless communications.  Through our diversely sponsored research, we approach the problems in the field from various aspects to resolve the bottleneck by developing innovative techniques and contributing in standards related to wireless communications such as Long Term Evolution (LTE), wireless regional, local, and personal area networks. In our research, we emphasize the necessity of the development of pioneering wireless communication systems, by which we took attention of various organizations such as National Science Foundation and private research labs to fund our research. On the other hand, we are collaborating with companies to enable the commercialization of our knowledge and experience in wireless communications and digital signal processing.

Current research interests are design of advanced waveforms for future communication systems, development of digital baseband signal processing algorithms, cognitive radio and software defined radio for opportunistic access to the spectrum for increased spectral efficiency, testing-measurement-modeling for algorithm design and evaluation, heterogeneous networks for the enhancement of the available resources  to enable advanced applications, and interference management/cancellation to overcome collisions for intelligent approach to heterogeneous/overlaid systems. Additional interests are multiple-input multiple output (MIMO) Systems, UWB communications, power line communications and smart grid.

The USF Surface Science Lab
Dr. Rudy Schlaf

Website

The Surface Science Lab, led by Dr. Schlaf, focuses on the investigation of phenomena at interfaces involving macro-molecular materials. Macro-molecular materials range from nano-crystalline semiconductors and metals to bio-molecules and electronic polymer materials. These materials are crucial for the development of advanced devices such as molecular transistors, plastic solar cells or bio-sensors. The Surface Science Lab uses photoemission spectroscopy integrated with in-vacuum sample preparation methods such as electrospray thin film deposition. Photoemission spectroscopy gives direct insight into the electronic structure of materials. Combined with its high surface sensitivity, detailed information of the interaction between materials at interfaces such as electrical contacts or exciton separation layers in solar cells can be investigated. Such insight is crucial for the development of novel devices and the synthesis of new materials. Other current projects at the Surface Science Lab include the investigation of spray processes for the rapid fabrication of biosensor substrates, the development of a patterning device for macro-molecular materials and the investigation of atomic layer deposition processes. Most projects at the Surface Science Lab are of interdisciplinary nature, and involve collaborations between engineers, chemists, biologists and physicists. Dr. Schlaf's research is currently funded through several National Science Foundation grants. Recent graduates of Dr. Schlaf's group found employment at companies like Solvay Inc., Diehl Defence, or National Instruments. The surface Science Lab also offers opportunities to undergraduate students to work as research associates within the framework of the College of Engineering Research Experience for Undergraduates program.

iWINLAB In vivo Wireless Information Networking Laboratory
Dr. Richard Gitlin

Website

The iWINLAB group focuses on studying novel in vivo channel models and signal processing that will facilitate the creation of new communications protocols accommodating the limitations of implanted devices, which are more restricted, from a communication and computing standpoint, than any devices that have ever been networked by human-created means. This knowledge will be useful to improve the design and implementation of the wirelessly controlled and communicating Miniature Anchored Robotic Videoscope (MARVEL) video system (i.e., a camera) and other embedded devices that are expected to create a paradigm shift in minimally invasive surgery. Another area of research is high throughput and robust wireless body area networks (WBANs) that enable information from in vivo devices such the MARVEL camera to be reliably transmitted to external devices through packet-based nodes/ gateways that are located on the human body.
