  • Cooperative Communications in the Fading Channel 

    Ahmed, Nasir; Aazhang, Behnaam (2005-03-01)
    Cooperative coding is a communication paradigm that pools distributed resources of different nodes in a network, such that the nodes act like a collaborative system instead of greedy adversarial participants. Cooperation ...
  • On Power Control with Finite Rate Feedback for Cooperative Relay Networks 

    Ahmed, Nasir; Khojastepour, Mohammad; Sabharwal, Ashutosh; Aazhang, Behnaam (2004-03-01)
    Power control strategies with finite rate feedback are studied for the cooperative channel. The main contribution of this paper is to show that quantized feedback information can lead to significant reduction in outage ...
  • Outage Minimization and Optimal Power Control for the Fading Relay Channel 

    Ahmed, Nasir; Khojastepour, Mohammad; Aazhang, Behnaam (2004-05-01)
    In this work, we show that in the wireless relay network, a tremendous savings in energy can be achieved by having side information at the transmitters and by employing power control. We present efficient protocols and the ...
