Tap coefficient string generator 103 converts to parallel a set of spreading codes generated by spreading code generator 102 for every one symbol, then gives them to the tap coefficient write terminal of programmable digital filter 106 via tap coefficient string write bus 104 and updates the tap coefficient of programmable digital filter 106 for every one information symbol. Upon the completion of reception of a section spread by the series of the Nth symbol, the shift register in programmable digital filter 106 is filled with the received signals of that section. If the series of the Nth symbol counted from the start of the long code is set as the tap coefficient of the programmable digital filter, correlative peaks appear at the matched filter output.
