Equalization and multiuser interference cancellation in CDMA systems

  title={Equalization and multiuser interference cancellation in CDMA systems},
  author={Stefano Tomasin and Nevio Benvenuto},
In this paper we propose a parallel interference cancellation (PIC) architecture for code division multiple access (CDMA) transmission over broadband wireless channel, which makes use of a block decision feedback equalizer (DFE) to remove inter-symbol interference (ISI) and whose overall complexity is much lower than equivalent (in terms of performance) existing structures. At the receiver, after IC, a block DFE operating at the chip-rate is applied, with both feedforward and feedback filters… CONTINUE READING
