Abstract
To provide a CDMA demodulation circuit and a CDMA demodulation method capable of maintaining good receiving characteristics even in a mobile communication environment. A fading pitch estimation portion estimates a time at which a level of a received input signal drops due to fading by monitoring fluctuation in the level provided by a rake combining portion. Before the level drops, a finger path assignment control portion controls assignment of path timing to a fingers portion performed by a finger path assignment portion.
