Abstract
A base sequence S(j) is not directly calculated but is indirectly calculated by the use of a numerical sequence M(n)=[v×n] mod p. A value of M(n) can be calculated by a recurrence formula without requiring modulo calculation. The value obtained is stored in a memory. M(n) satisfies S(j)=M(S(j−1)). By determining an initial value of S(j) and interleaving the value of M(n) stored in the memory, the base sequence S(j) can be calculated without modulo calculation.
