Abstract:
A rake receiver comprising:first decimating means for extracting received signals in order to perform synchronous acquisition;second decimating means for extracting received signals from a synchronously acquired clock;,selecting means for switchingly outputting a PN code and a wideband PN code;first despreading means which despreads the received signals extracted by said first decimating means with said PN code to supply them to time tracking means; andsecond despreading means for despreading an outputting of said second decimating means with an outputting of said selecting means, said second despreading means which despreads the received signals extracted by said second decimating means with said PN code to supply obtained pilot data are to pilot carrier tracking means, and which despreads the received signals extracted by said second decimating means with said wideband PN code to supply obtained data to data path demodulating means;wherein the data which are to be supplied to said pilot carrier tracking means and said data path demodulating means are despread by using said second despreading means which is common to these means.
