<p>A code division multiplex signal receiving device which uses the same code string as a diffusion code string on a transmitting side to subject a received signal to a reverse diffusion processing and demodulate transmission data, wherein a cross-correlation detection unit calculates, for each symbol, a cross-correlation value between a diffusion code string for diffusion-modulating transmission data addressed to own station and a diffusion code string for diffusion-modulating transmission data addressed to another station, a judging unit determines whether or not the calculated cross-correlation value has exceeded a threshold value, and a switch unit stops the inputting to a decoding unit of the portion of a received signal corresponding to the entire or part of a period of a symbol where the cross-correlation value exceeds the threshold value.</p> |
