Abstract The multipath search and distribution method suitable for the RAKE receiver in wideband CDMA system includes the steps of: scanning the multipath to be selected continuously to obtain relative energy information; multipath phase treatment of the relative energy information; selecting out M phases with stronger energy by the controller and regular checking, comparison and search of multipath phase energy, demodulation peak phase energy for re-distribution of phase, loosing lock monitoring treatment and multiple unit and in phase demodulation monitoring treatment. The present invention can reach the accurate search and reliable distribution of multipath to raise the performance of RAKE reception.
