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.
