Meeting and Seminar Archive: Date:  March , 2010 Subject: An overview of various physical and MAC layer research and developmental issues in 4G cellular systems Speaker: Joydeep Acharya, Wireless Systems Research Lab (WSRL), Hitachi America Ltd Abstract: Cellular networks are experiencing a rapid growth in terms of services provided and customer base. To enable new features such as faster data rate, better support for video and real time applications, there needs to be fundamental changes in the underlying radio level technology. This talk highlights the key features of some of these technologies. It also explains how multiple companies after doing R&D, meet and discuss their results which ultimately leads to the evolution of a generation of cellular systems. Speaker Bio: Joydeep Acharya received his B.Tech. degree in Electronics and Electrical Communications from Indian Institute of Technology, Kharagpur in 2001 and M.S. and PhD. in Electrical Engineering from Rutgers University in 2005 and 2009 respectively. From 2001 - 2002, he worked as a research consultant in GS Sanyal School of Telecommunications, IIT Kharagpur on Physical Layer design of WCDMA. From 2003-2009, he did his doctoral research at the Wireless Information Networks Laboratory (WINLAB), Rutgers University. His doctoral research topics included spectrum regulation for wireless systems, resource allocation and microeconomics principles as applied to wireless communications, MIMO and OFDM systems. Currently he is a researcher at the Wireless Systems Research Lab (WSRL), Hitachi America Ltd. where he is involved in physical layer R&D issues of LTE and LTE-Advanced with emphasis on downlink multi-user MIMO algorithms and multi base station coordination.
