  • Distorted Channel Capacity: A Geometrical Approach 

    Das, Suman; Cavallaro, Joseph R.; Erkip, Elza; Aazhang, Behnaam (2000-06-20)
    Shannon's capacity result has often been used as a benchmark to compare the performance of practical codes. Shannon's theorem helps us to calculate the maximum rate at which data can be transferred without making any errors. ...
  • 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, ...
  • Improving Performance of a Space-Time Turbo Code in a Rayleigh Faded Channel 

    Huang, Everest; Gatherer, Alan; Muharemovic, Tarik; Hocevar , Dale (2001-10-20)
    Starting with an ordinary parallel concatenated turbo encoder in a block fading Rayleigh channel, we introduce bit-interleaving of the outputs, not for time diversity, but to increase the coding gain. We develop a guideline ...
  • 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 ...
  • 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 ...
