Abstract
A RAKE receiver includes an arithmetic circuit for weighting coefficients. The arithmetic circuit obtains the signal power for each path from the reception amplitude on the path which is detected by a transmission path characteristics detector, and also obtains the interference powers from the reception amplitudes on two other paths which are respectively detected by transmission path characteristics detectors. The arithmetic circuit then calculates the weighting coefficients on the basis of the these signal powers and interference powers. The weighting coefficients are respectively supplied to weighting multipliers, thereby weighting the reception signals from the respective paths. A symbol synthesizer performs symbol synthesis of the resultant signals.
