Abstract:
A spread spectrum receiver in a CDMA system comprising:a radio section for detecting spread spectrum input signals and converting them to baseband signals;a path search section for performing a path search with respect to said baseband signals to determine the phase difference in each path;a DLL section for despreading and demodulating said baseband signals for each path, at a timing indicated by said path search section;a timing adjusting section for truing up the phase of the demodulated signals from said DLL section with a predetermined timing and outputting the signals, respectively; anda RAKE synthesis section for RAKE-synthesizing the signals from said timing adjusting section;said timing adjusting section comprising:a buffer section for storing and holding the signals from said DLL section based on the timing indicated by said path search section, and outputting signals in an address indicated by a read signal; anda read signal control section for indicating an address and a timing by means of said read signal, so that the signals in each path held by said buffer section is output with the phase being trued up.
