CDMA reception apparatus and power control method therefor |
摘要 |
A CDMA reception apparatus has a plurality of fingers and performs RAKE reception by RAKE-combining outputs from the plurality of fingers. The apparatus includes a multi-path detecting section and delay profile generating section. The multi-path detecting section detects a multi-path consisting of a plurality of radio waves arriving with some delay times by despreading a reception signal. The delay profile generating section generates a delay profile by obtaining the reception power levels of all reception signals in the multi-path detected by the multi-path detecting section. A difference di in level between the signal having the ith highest level and the signal having the (i+1)th highest level of the data of the delay profile is obtained. The operation of a finger corresponding to a signal having a low level is stopped on the basis of the difference di and a predetermined threshold dTH. |
