Waveform estimating section 302 observes the amplitude and phase of pilot signals outputted from pilot despreading section 301, and estimates the amplitude, frequency and phase of the pilot signals having no interference. Sine wave generating section 303 generates pilot signals of sine wave of the estimated amplitude, frequency and phase. Coherent detecting section 305 corrects the phase shift of data signals outputted from data channel despreading section 304, using the generated pilot signals.

Une section d'évaluation de formes d'onde 302 observe l'amplitude et la phase de signaux pilotes produits par une section de désétalement de signaux pilotes 301, et évalue l'amplitude, la fréquence et la phase de signaux pilotes non parasités. Une section de génération d'ondes sinusoïdales 303 produit des signaux pilotes sinusoïdaux dont l'amplitude, la fréquence et la phase sont égales aux valeurs évaluées. Une section de détection de cohérence 305 corrige le déphasage des signaux de données produits par la section de désétalement de canaux de données 304 au moyen des signaux pilotes produits.
