<p>[PROBLEMS] This object is aimed to process and create a spreading carrier and a despreading carrier without performing an active synchronization operation. [MEANS FOR SOLVING PROBLEMS] A carrier processing device comprises a noise signal supply unit for outputting an irregular noise signal including noise, a spreading carrier processing means for processing the noise signal into a spreading carrier, and a despreading carrier processing means for processing the noise signal into a despreading carrier. The noise signal supply unit supplies the noise signal commonly to the two carrier processing means. The spreading carrier processing means and the despreading carrier processing means process, by sharing the noise signal, the noise signal into the spreading carrier and the dispreading carrier having a cross-correlation and an irregularity and obtains a pair of the spreading carrier and the dispreading carrier in which the product of a value of the spreading carrier and a value of the dispreading carrier shows a constant value regardless of the values of the carriers.</p> |
