講演内容 (Abstract)

In multi-user communication systems without central control, random access is a suitable option due to its decentralized nature. This talk is concerned with the decentralized power allocation problem in random-access systems. Multi-user detection (MUD) is assumed at the receiver to enhance the multi-packet reception (MPR) capability. We consider a decentralized random power transmission strategy, in which each user selects its transmit power level randomly according to a power distribution conditioned on its own channel state. Our focus is on the design of this distribution such that the system packet throughput is maximized under rate and power constraints. A main finding is that the supports of the optimal power distributions are of discrete nature. This finding greatly simplifies the distribution optimization problem. Numerical results demonstrate that the proposed scheme can achieve significant performance improvement compared with conventional single-user detection (SUD) based schemes and offer flexible tradeoff between the system throughput and power consumption. Throughput gain of several folds is observed in fading channels.

講演者略歴 (Biography)

Prof. Li Ping received his Ph.D. degree at Glasgow University in 1990. He lectured at Department of Electronic Engineering, Melbourne University, from 1990 to 1992, and worked as a research staff at Telecom Australia Research Laboratories from 1993 to 1995. Since January 1996, he has been with the Department of Electronic Engineering, City University of Hong Kong, where he is now a chair professor of information engineering.

Prof. Li Ping received the IEE J J Thomson premium in 1993, the Croucher Foundation Award in 2005 and a British Royal Academy of Engineering Distinguished Visiting Fellowship in 2010. He served as a member of the Board of Governors for IEEE Information Theory Society from 2010 to 2012 and is a fellow of IEEE.
