RADIO RECEPTION APPARATUS AND RADIO RECEPTION METHOD

摘要

A maximum delay time setting block (106) sets a delay time width W’ for removing interference by using a delay profile. In the present embodiment, a delay spread is calculated and up to a delay wave contained in the delay spread is set as W’. Firstly, a delay spread calculator (1061) of the maximum delay time setting block (106) calculates a delay spread. That is, a standard deviation of the delay profile is calculated. The delay spread calculated is output to a maximum delay time decider (1062). In the maximum delay time decider (1062), the maximum delay time (window width) W’ is decided in accordance with the delay spread. Accordingly, up to the delay wave contained in the maximum delay time thus decided is an object of interference removal in the joint detection. Thus, without lowering the efficiency of the RAKE synthesis, it is possible to optimize the interference removal efficiency and the calculation size.
