Talk Title: Communications with Limited and Delayed Feedback: Towards the Fundamental Performance-vs-Feedback Tradeoff
Abstract: In many multiuser wireless communications scenarios, good feedback is a crucial ingredient that facilitates improved performance. While being useful, perfect feedback is also hard and time-consuming to obtain. With this challenge as a starting point, the work seeks to address the simple yet elusive and fundamental question of ``HOW MUCH QUALITY of feedback, AND WHEN, must one send to achieve a certain degrees-of-freedom (DoF) performance in specific settings of multiuser communications''. The work manages to concisely describe the DoF region in a very broad setting corresponding to a general feedback process that, at any point in time, may or may not provide channel state information at the transmitter (CSIT) - of some arbitrary quality - for any past, current or future channel (fading) realization. Under standard assumptions, and under the assumption of sufficiently good delayed CSIT, the work concisely captures the effect of the quality of CSIT offered at any time, about any channel. The generality allows for consideration of many channel models (block and non-block fading models), as well as incorporation of many previously considered settings. This was achieved for the two user MISO-BC, and was then immediately extended to the MIMO BC and MIMO IC settings.
Biography: Jinyuan Chen is currently a visiting scholar at University of California, Irvine. He received the PhD degree from EURECOM/Telecom Paris Tech in June 2013, the M.Sc. degree from Beijing University of Posts and Telecommunications in 2010, and the B.Sc. degree from Tianjin University in 2007. His industry experience includes doing internship at Ericsson, Beijing, in 2009. He was a recipient of Outstanding Graduate award and of Tsang Hin Chi scholarship. His research interests include network information theory, communication theory, interference management and limited feedback.
