Abstract

The use of CDMA makes third generation wireless systems interference limited rather than noise limited. The research for new methods to reduce interference and increase efficiency lead us to formulate a signaling method where fast impulsive silence states are mapped on zero-energy symbols. The theoretical formulation of the optimum two-states receiver is reported. The proposed communication scheme has been merged into the 3GPP standard W-CDMA communication system and the performance of the two-states RAKE receiver has been simulated in a multipath fading wireless channel. Comparisons with the traditional one-state RAKE receiver have been also reported.
