Abstract

In a PN code generating apparatus, a code of the predetermined number of stages is generated using primitive polynomial G(x), then the code content of each stage is shifted to the next stage. And a state setting section obtains a code state of the PN code generating section after shifted the specific times from a code state of the PN code generating apparatus at a certain time, based on x i modG(x) as the number of shift times is i.
