RAKE Receiver

Abstract

U radu je dan teorijski opis CDMA sustava i njegovih osnovnih načela rada. Uz tehniku raspršenog spektra, opisana je i kontrola snage te ortogonalni kodovi. Objašnjen je dizajn RAKE prijemnika, njegova funkcija i način rada. Na temelju simulacije napravljena je analiza utjecaja parametara prijemnika na kvalitetu detektiranog signala u različitim propagacijskim scenarijima.The paper presents a theoretical description of the CDMA system and it's basic principles of operation. The spread spectrum technique is described along with power control and orthogonal codes. The design of RAKE receiver is explained as it's function and operation technique. Analysis of influence of different parameters of receiver on the quality of detected signal in different propagation scenarios is made on the base of simulation
