Xingkai Bao

Xingkai Bao is a Ph.D. candidate in the wireless communications program in the Department of Electrical and Computer Engineering

Xingkai Bao is pursuing research in the areas of communication theory, wireless communications, and sensor networks as a Ph.D. student under the guidance of Prof Tiffany Jing Li. His recent research includes distributed adaptive network coding, rate-less LDPC codes, joint channel-network coding, cooperative networks, and wireless localization for ad-hoc and sensory networks. His research not only helps enhance the reliability and throughput for wireless networks, but will also reduce power consumption and improve performance for emerging green communications systems and networks. His research results are published in more than 10 papers in peer-reviewed international journals and conferences.

In one recent publication, Bao and Prof Li developed an efficient method of wireless localization through the novel exploitation of distributed space-time codes and maximum likelihood estimation. This new signal processing technique can solve the problems in which the wireless localization accuracy suffers from random channel fades and highly obstructed (i.e. non-line-of-sight) conditions. Monte Carlo simulation studies show that this scheme reduces the localization error significantly in both urban areas and indoor environments, where wireless localization is most challenging.

Bao won the best student poster award (first place) in the Wireless and Optical Communications Conference (WOCC) in May 2009. Earlier in April, he received recognition in the 2009 Academic Symposium: A Tradition of Excellence at Lehigh University. Bao is also a recipient of the Rossin Doctoral Fellowship. He holds a BS and an MS degree in Communication and Information Science from the Southeast University of China, one of the top Chinese universities located in Nanjing, Jiangsu Province. In 2007 and 2008, he spent two summers with Philips Research North America in White Plains, NJ, giving him practical experience in the wireless industries. He filed 3 patents in the area of wireless sensory and control networks during these internships.
