Abstract: PURPOSE: A rake receiver capable of compensating channel estimation delay is provided to use a finite impulse response filter, and to install a data buffer for buffering data during channel estimation and compensation periods, thereby according a channel value by a pilot signal from a shared pilot channel or a dedicated physical control channel with demodulated data. CONSTITUTION: Many fingers(100) estimate and compensate channels by spreading receiving signals, and output symbols. A combiner(200) combines the outputted symbols. A decoder(300) decodes output data of the combiner(200). Each of the fingers(100) comprises as follows. A despreader(110) receives wireless signals including a shared pilot signal and a traffic signal, and despreads the wireless signals. A channel estimating device(A) selectively outputs a channel estimation value estimated by the shared pilot signal and a dedicated physical control pilot signal, and buffers a traffic signal of the despread signals to output the buffered signal. An multiplier(160) multiplies the channel estimation value by the buffered value, and outputs a data value whose channel influence is compensated.
