A CDMA receiving apparatus is provided with a profile calculator (107) for calculating a profile of a reception signal and a tap controller (108) for determining the number of needed taps and the timing from the profile. An adaptive despreading filter (110) for performing filter processing on a reception signal r, an autocorrelative inverse matrix calculator (113) and an adaptive controller (111) for controlling a filter coefficient of an adaptive despreading filter receive instructions of the tap length and the timing from the tap controller 10 to calculate only the tap position determined. <IMAGE> |
