Chittabrata Ghosh
Senior ResearcherBerkeley, CA, USA
Since July 2011, I am working as a Senior Researcher at NRC, Berkeley, CA, USA. Before joining NRC, I was pursuing PostDoctoral Research in the Electrical Engineering Department of University of Washington, Seattle for two years. I was working with Prof. Sumit Roy with special interest in defining coexistence solutions for heterogeneous cognitive wireless networks in the TV White Space. We also pursued intricate analysis of heterogeneous coexistence using Continuous Time Markov Chains and defining an information theoretic framework based on Dirty Paper Coding.
Professional Activities
I am an active IEEE Member and the Vice Chair of TCSIM for the Asian counterpart. I serve on the TPCs of esteemed Conferences and invited for peer-review of journal paper submissions like IEEE Trans. of Wireless Communications, IEEE Journal on Special Areas in Communications, IEEE Transaction on Communications, to name a few.
Research Interests
I) Cross-layer architectural design for future WiFi networks for better performance in terms of energy and throughput;
II) Defining innovative coexistence mechanisms for WiFi networks with heterogeneous networks operating on the same spectrum, e.g., the IEEE 802.11af WiFi Networks operating with IEEE 802.22 Networks in the TV White Space.
III) Data mining techniques and machine learning algorithms in cognitive radio networks
