Research Interests:
		Area of Interest: Communication theory and signal processing for communications systems. Research applies information theory, communication theory, and signal processing to analyze and design algorithms to improve the throughput, robustness, and reliability of communications systems. Current research interests focus on developing practical coding schemes that approach the information theoretic limits associated with broadcasting information over linear Gaussian channels to multiple users. Applications include Wireless LANs utilizing multiple antennas at the transmitter and receiver, satellite communications, asynchronous digital subscriber lines, digital video broadcast, and almost any wireless communication system.
	Uncoordinated Multiple Access in Optical Communications:
		Introduction: Though it promises high bandwidths, the optical medium is not popular in local area networks. This is because current optical networks do not offer the ease of use and setup that an uncoordinated multiple access network such as Ethernet offers. We show in our demonstrator that it is possible for an optical networks to exhibit these desirable properties while maintaining the high optical transmission rates. With careful design of unique channel codes we have demonstrated the feasibility of uncoordinated multiple access in optical networks. Using commercial off the shelf components, we demonstrated an optical network with data bandwidth more than an order of magnitude above that of Ethernet. [OCDMA Project Details]
