    • Efficient Methods for Identification of Volterra Filters 

      Nowak, Robert David; Van Veen, Barry D. (1994)
      A major drawback of the truncated Volterra series or "Volterra filter" for system identification is the large number of parameters required by the standard filter structure. The corresponding estimation problem requires ...
    • Efficient MIMO equalization for downlink multi-code CDMA: complexity optimization and comparative study 

      Guo, Yuanbin; Zhang, Jianzhong (Charlie); McCain, Dennis; Cavallaro, Joseph R. (2004-11-01)
      In this paper, we present an efficient LMMSE chip equalizer to suppress the interference caused by the multipath fading channel in the MIMO multi-code CDMA downlink. The block-Toeplitz structure in the correlation matrix ...
