A CDMA signal receiving apparatus for a base station includes a spread-spectrum demodulation section which has a plurality of channel-signal processing sections and a common-signal processing section. Each of the channel-signal processing section receives a digital spread-spectrum modulated base band signal and performs a reception processing of a channel signal by means of spread-spectrum demodulation using common data, wherein the channel signal refers to a digital spread-spectrum demodulated base band signal destined to the channel of concern. The common-signal processing section computes, from the digital spread-spectrum modulated base band signal, values required in common to all of the channel-signal processing sections for the spread-spectrum demodulation to be processed in each of the channel-signal processing sections, and outputs the values as the common data.
