PHASE OFFSET CALCULATING METHOD OF DUAL CODE

摘要

PURPOSE: A phase offset calculating method of dual code is provided to simplify the calculation method of phase offset and greatly expand the selection condition to component comprising dual code. CONSTITUTION: The phase offset calculating method of dual code comprises: the first step obtaining integers g and m satisfying the first condition of gcd(g.m)=1 and or dmg=n; the second step checking the existence of integer j satisfying the second condition of Ag(C)=gj(mod m) by using the integers g and m; the third step repeating the first and second steps until the first and second conditions are satisfied; and the forth step calculating phase offset of dual code.
