<p>In a CDMA mobile station or the like, there are provided a plurality of despreaders (5a, 5b, 5c, 5d) connected to a common receiving system for effecting despreadings for respective multi-paths. A first combiner (6) is used to obtain a combined signal by combining signals outputted from the plurality of despreaders (5a, 5b, 5c, 5d) with phase differences between the multi-paths maintained. A fading pitch sensor (7) is used to measures the fading pitch fD from the combined signal. In this way, the fading pitch can be determined with high precision without using a plurality of branches (antennas) receiving signals which can be assumed to have no correlation therebetween.</p> |
