Abstract
A correlation unit,de-spreads reception signal in a reception physical channel and a physical channel for channel estimation with a de-spread timing signal designated by a path control unit,and supplies the portions of reception symbols in the de-spread reception signal, corresponding to the pilot symbols and the reception symbols corresponding to the reception physical channel, to weighting coefficient estimation units,and a weighting circuit,, respectively. The weighting coefficient estimation unit,carries out channel estimation corresponding to paths for individual finger units,-,through,-,. The weighting circuit,multiplies a complex conjugate of the estimated weighting coefficient by the reception signal to produce the multiplication result to a RAKE combiner unit,. The RAKE combiner unit,carries out maximum-ratio combining of the weighted reception signals supplied from the finger units,-,through,-,and produces the combination result via an output terminal
