    摘要： 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.

    摘要： There is provided a receiving apparatus receiving and processing spread spectrum radio signals comprising a plurality of antenna branches, a selective combiner circuit, an evaluation circuit and a control circuit. Each antenna branch is configured to be switched between active and inactive. The evaluation circuit evaluates signals demodulated by each antenna branch and combined by the selective combiner. The control circuit switches off an antenna branch of lower quality of received signals in a case where a figure-of-merit of the selective-combined signal is satisfactory so that power consumption may be reduced.
