    • Delay and DOA estimation in CDMA communication systems via maximum likelihood techniques 

      Madyastha, Raghu; Aazhang, Behnaam (1997-10-20)
      We present a maximum likelihood method for delay estimation in a CDMA wireless communication system. An antenna array is used at the receiver, which facilitates the concomitant estimation of the direction of arrival (DOA) ...
    • Distributed Cooperative Communications in Wireless Networks 

      Khojastepour, Mohammad (2005-01-01)
      The primary challenge in communication over wireless networks, unlike wireline networks, is the existence of interference and channel variations (fading). Having more users at higher data rates means that current ...
    • Exploiting Feedback in Cooperative Relay Networks 

      Ahmed, Nasir (2005-08-01)
      Recent results on multiple antenna transmission techniques have shown great po- tential in their ability to improve the overall performance in fading channels. Despite the promise shown by employing multiple antenna's, ...
    • Non-coherent and Partially Coherent Space-Time Constellations 

      Borran, Mohammad Jaber (2003-06-01)
      With the rapid growth of wireless networks and multimedia applications, next generation cellular systems are expected to support data rates that are orders of magnitude higher than those currently available. Due to the ...
