Frequency-domain interference cancellation and nonlinear equalization for CDMA systems

  title={Frequency-domain interference cancellation and nonlinear equalization for CDMA systems},
  author={Stefano Tomasin and Nevio Benvenuto},
  journal={IEEE Transactions on Wireless Communications},
In wireless broadband communications using code division multiple access (CDMA), interference cancellation (IC) techniques have been proposed to reduce multiuser access interference (MAI); however, their performance is limited by complexity constraints that still favor the use of rake receivers. In this paper, we propose an IC architecture that makes use of a block decision feedback equalizer (DFE) to remove intersymbol interference (ISI) and whose overall complexity is much lower than… CONTINUE READING
