  • User Cooperation Diversity--Part II: Implementation Aspects and Performance Analysis 

    Sendonaris, Andrew; Erkip, Elza; Aazhang, Behnaam (2003-11-20)
    This is the second in a two-part series of papers on a new form of spatial diversity, where diversity gains are achieved through the cooperation of mobile users. Part I described the user cooperation concept and proposed ...
  • User Cooperation Diversity--Part I: System Description 

    Sendonaris, Andrew; Erkip, Elza; Aazhang, Behnaam (2003-11-20)
    Mobile users' data rate and quality of service are limited by the fact that, within the duration of any given call, they experience severe variations in signal attenuation, thereby necessitating the use of some type of ...
  • Advanced Techniques for Next-Generation Wireless Systems 

    Sendonaris, Andrew (1999-08-20)
    In order to meet the demands of next-generation wireless systems, which will be required to support multirate multimedia at high data rates, it is necessary to employ advanced algorithms and techniques that enable the ...
  • Multiuser detection in fast-fading multipath environments 

    Sayeed, Akbar M.; Sendonaris, Andrew; Aazhang, Behnaam (1998-12-20)
    We propose a new framework for multiuser detection in fast-fading channels that are encountered in many mobile communication scenarios. Existing multiuser RAKE receivers, developed to combat multipath fading and multiuser ...
  • Joint signaling strategies for approaching the capacity of twisted-pair channels 

    Sendonaris, Andrew; Veeravalli, Venugopal V.; Aazhang, Behnaam (1998-10-20)
    A technique is presented for jointly optimizing the signaling in the two directions of transmission on a twisted-pair communications channel. It is then applied to twisted-pair channel models with monotonic channel response ...
  • Increasing uplink capacity via user cooperation diversity 

    Sendonaris, Andrew; Erkip, Elza; Aazhang, Behnaam (1998-08-20)
    Mobile users' capacity is limited by the fact that within the duration of any given call, they experience severe variations in signal attenuation, thereby necessitating the use of some type of diversity. We are proposing ...
  • Multiuser detectors for fast-fading multipath channels 

    Sayeed, Akbar M.; Sendonaris, Andrew; Aazhang, Behnaam (1997-10-20)
    We propose a new framework for multiuser detection in fast fading channels that are encountered in many mobile communication scenarios. The detectors proposed in this paper employ a novel multiuser receiver structure based ...
