Abstract
The SIR values of multi-paths obtained by a transmission path estimator are accumulated by an integrator at very cycle of a pilot signal, an average value for sufficiently long period is calculated by an average value calculator, a reference value is divided by a divider and applied as a control coefficient to multipliers, where it is multiplied by the SIR values, and the weight values of multi-paths are obtained. As for the despreaded data from a despreading unit, the timing of all data is synchronized in buffers, the data is complex multiplied by the above-mentioned weight values in multipliers, and RAKE is synthesized by adding in an adder, and outputted as final demodulated data to a soft decision unit.
