Intrusion Control in WCDMA using DRR

Decorrelating Rake Receiver is used in Wideband Code Division Multiple Access to suppress the intrusion in the received FM signal. In order to increase the signal to noise ratio at the receiver, MRC technique at the receiver is used. A separate correlation receiver be granted intended for every multipath signals, the time-shifted versions of the original signal be attempted to accumulate at the DRR receiver. Autocorrelation is reduced inside a signal or cross correlation in a set of signal. This process is achieved by multipath components which are practically uncorrelated from another when their relative propagation delay exceeds a chip period. This paper presents the basics of MRC technique used in DRR, Rake receiver, and design of RR in DRR. Also the usage o f DRR receiver is introduced in WCDMA
