Abstract:
1. A RAKE combining circuit comprising: at least two fingers that are circuits for demodulating pilot symbols as well as receive data and outputting not only an instantaneous pilot symbol value resulting from correcting a phase of one demodulated pilot symbol itself in response to phase deviation of the one demodulated pilot symbol but also a pilot symbol value resulting from correcting a phase of the same pilot symbol corresponding to the instantaneous pilot symbol value in response to averaged phase deviation of a plurality of demodulated pilot symbols, a weight factor generation circuit for generating weight factors corresponding to demodulated receive data outputted from the respective fingers on the basis of a difference between the instantaneous pilot symbol value and the pilot symbol value, and a combiner for weighting and combining the demodulated receive data outputted from the respective fingers by using the weight factors outputted from the weight factor generation circuit.
