    • Achievable rate regions and performance comparison of half duplex bi-directional relaying protocols 

      Kim, Sang Joon; Devroye, Natasha; Mitran, Patrick; Tarokh, Vahid (Institute of Electrical and Electronics Engineers, 2011-10)
      In a bi-directional relay channel, two nodes wish to exchange independent messages over a shared wireless half-duplex channel with the help of a relay. In this paper, we derive achievable rate regions for four new half-duplex ...
    • An Information Theoretic Take on Time Reversal for Non-Stationary Channels 

      Setlur, Pawan; Devroye, Natasha (Institute of Electrical and Electronics Engineers, 2013-04)
      It has been shown that time-reversal (TR) techniques focus energy back to the dominant scatters, lead to superresolution focusing, and gains in detection. Time reversal has so far mainly been studied when the channel ...
    • Multipath Exploitation in Non-LOS Urban Synthetic Aperture Radar 

      Setlur, Pawan; Negishi, Tadahiro; Devroye, Natasha; Erricolo, Danilo (Institute of Electrical and Electronics Engineers, 2014-02)
      Multipath is exploited to image targets that are hidden due to lack of line of sight (LOS) path in urban environments. Urban radar scenes include building walls, therefore creating reflections causing multipath returns. ...
    • New inner and outer bounds for the memoryless cognitive interference channel and some new capacity results 

      Rini, Stefano; Tuninetti, Daniela; Devroye, Natasha (Institute of Electrical and Electronics Engineers, 2011-07)
      The cognitive interference channel is a two-user interference channel in which one transmitter is non-causally provided with the message of the other transmitter. This channel model has been extensively studied in the past ...
