    • MultiHop Communication is Order Optimal for Homogeneous Sensor Networks 

      Chakrabarti, Arnab; Sabharwal, Ashutosh; Aazhang, Behnaam (2004-04-01)
      The main goal of this paper is to show that multi-hop single-user communication achieves the per node transport capacity of O(lnN/N) in homogeneous sensor networks, making it order-optimal. Our contributions in this paper ...
    • On Beamforming with Finite Rate Feedback in Multiple Antenna Systems 

      Mukkavilli, Krishna Kiran; Sabharwal, Ashutosh; Erkip, Elza; Aazhang, Behnaam (2003-10-20)
      In this paper, we study a multiple antenna system where the transmitter is equipped with quantized information about instantaneous channel realizations. Assuming that the transmitter uses the quantized information for ...
