In an arrangement for receiving CDMA signals, insertion of guard intervals is rendered unnecessary and transmission efficiency loss is suppressed, along with greatly reducing the computational burden of weight calculations. Impulse responses of a transmission channel are obtained by time-domain signal processing, the impulse responses are Fourier transformed and converted into frequency domain signals, equalizing filter weights are calculated using the frequency domain impulse responses, the calculated frequency domain weights are converted to time domain weights using an inverse Fourier transform, the received signals are filtered using time-domain signal processing, and data signals are demodulated by despreading the equalized signals.
