The response time is one of the main constraints in bluetooth synchronization and message transfer. This paper provides a novel approach for calculating a probabilistic worst-case response-time for messages in the bluetooth. We are using frequency hopping mechanism in order to retrieve the useful distribution of pockets instead of the worst-case scenario in bluetooth communication. Since the bluetooth systems are not synchronized, the number of bluetooth hops which it overlaps will depend not just on the 802.11 packet's length but also on the time offset between the packet and the hops. The best option to avoid the overlap problem is the time period. This analysis was concerned only with the timing relationships between an 802.11 packet and the bluetooth hops.Keywords

Several types of Rake Receivers like A-Rake, S-Rake, P-Rake, Adaptive frequency Rake, Time frequency Rake, Conventional MMSE Rake and Adaptive MMSE rake are used for WCDMA. In this paper we observed that the BER performance of the Adoptive MMSE Rake receiver gives better result in WCDMA. The comparative analysis proved that the Adaptive MMSE Rake Receiver is much better than Conventional Rake Receiver. Both Genetic Algorithm (GA) and as well as Conventional algorithm are derived for WCDMA environment.Keywords

The third-generation universal mobile telecommunications system uses the high signal bandwidth for the WCDMA system (5 MHz) allows the received signal to be split into distinct multipath with high resolution. The rake receiver combines the received signals from different paths into a composite signal with substantially better characteristics for demodulation than a single path and maximizing the amount of received signal energy. This paper derived both the combination of rake receiver and equalizer. The output of the rake receiver is fed to the equalizer for filter the white noise presence in the receiving signal. This will give us a good reception of WCDMA signal at the receiver end.Keywords
