  • Degrees of Freedom for Mutually Interfering Broadcast Channels

    Inkyu Lee,
    Korea UniversityAbstract: In this talk, we present an expression of spatial degrees of
    freedom (DOF) for two mutually interfering broadcast channels (IFBC) as
    a function of arbitrary numbers of transmit antennas and users. The
    lower bound on the DOF is obtained by showing that the zero-forcing
    solution suffices to achieve all the DOF. Also, the upper bound which
    coincides with the lower bound is shown using Jafar's earlier work. From
    the derived result, we observe that disabling receive cooperation of the
    MIMO interference channel causes the DOF loss. Additionally, we propose
    a linear precoding scheme for the IFBC by extending one designed for
    broadcast channels with an aim of maximizing the sum rate performance.
    We utilize the fact that the precoding matrices in stationary point
    always satisfy the zero-gradient condition. Our result is confirmed
    through numerical simulations on the sum rate performance of the
    proposed precoding technique.Biography: Inkyu Lee is currently a visiting scholar at USC. Prof. Lee
    received the B.S. degree (Hon.) in control and instrumentation
    engineering from Seoul National University, Seoul, Korea in 1990, and
    the M.S. and Ph.D. degrees in electrical engineering from Stanford
    University in 1992 and 1995, respectively. From 1995 to 2001, he was a
    Member of Technical Staff at Bell Laboratories, Lucent Technologies,
    where he studied high-speed wireless system design. He later worked for
    Agere Systems (formerly the Microelectronics Group of Lucent
    Technologies), Murray Hill, NJ, as a Distinguished Member of Technical
    Staff from 2001 to 2002. In September 2002, he joined the faculty of
    Korea University, Seoul, Korea, where he is currently a Professor in the
    School of Electrical Engineering. His research interests include digital
    communications, signal processing, and coding techniques applied to
    wireless systems with an emphasis on MIMO-OFDM. Dr. Lee currently serves
    as an Associate Editor for the IEEE TRANSACTIONS ON COMMUNICATIONS and
    the IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS. Also, he has been a
    Chief Guest Editor for the IEEE JOURNAL ON SELECTED AREAS IN
    COMMUNICATIONS (Special Issue on 4G Wireless Systems).Host: Giuseppe Caire, caire@usc.edu, EEB 528, x07326
