Diversity and Multiplexing: A Fundamental Tradeoff in Wireless Systems

David Tse, University of California, Berkeley:

Monday April 14, 2003 1:30 pm, Rutgers University, CoRE 431:

The amount of diversity and the total number of degrees of freedom are two important resources in a wireless system. Traditionally they have been considered in isolation. We propose the point of view of describing the performance of communication schemes as a tradeoff between the amount of these two resources actually utilized.The optimal tradeoff achievable by any scheme provides then a fundamental benchmark with respect to which actual schemes can be judged. We give several examples on which this framework can be applied: 1) point-to-point MIMO links, 2) multiple access MIMO channels 3) frequency-selective ISI channels; 4) cooperative relaying systems.
