Abstract :
In this work, we derive a blind MMSE equalization algorithm suitable for long-coded CDMA systems in the framework of multiple base station receivers. We also introduce a new semiblind equalization algorithm that takes advantage of the pilot signal available in the uplink of WCDMA systems, exhibiting improved performance as supported by our numerical simulations.
