چکیده

3G mobile communications is advanced and emerging technology in the field of wireless communication also providing facilities like multimedia accessing, internet services, higher capacity of data rates and multiple services for same connection. The Rake receiver involves descrambling, dispreading, channel estimation and fading cancellation. The main principle behind Rake receiver is that they exploit multipath propagation by receiving the multipath components of the transmitted signal separately and combining their energies. The Rake receiver is used to tackle the problems of time dispersion (echoes) caused by multipath propagation in mobile communication. The above paper provides an introductory background on 3G communication and various objectives of 3G. To solve the above mention problems we have proposed architecture of WCDMA Rake receiver which is implemented in VHDL. The synthesis done by Xillling ISE 9.2i and simulation is done by ModelSim SE 6.3f. Keyword: 3G, multipath propagation, WCDMA, spreading, scrambling, fading cancellation.

System Performance Gain by Interference Cancellation in WCDMA Dedicated and High-Speed Downlink Channels

A large number of the existing and planned 3G networks rely on the 3GPP WCDMA standard. Since the downlink of WCDMA systems is usually interference limited, interference cancellation algorithms that reduce the interference on the desired signal can significantly improve the system capacity. In this paper, the system-level performance gain that can be achieved by interference cancellation on the...
