Abstract :
A ZCZ(Zero Correlation Zone) sequence set plays an important role in the research of CDMA, ultrasonic imaging, position control and so on. Its a set of perfect sequences which has a property about cross-correlation. We treat the set of perfect sequences as a zero set of quadratic equations and try to simplify these equations. We prove "Decomposition Theorem" of perfect sequences and the theorem convert the problem of the structures of perfect sequences into the problem of the structures of quasi-perfect sequences which we named. Parameterizing of perfect sequences of easy case and quasi-perfect sequences lead us to the parameterization of perfect sequences of arbitrary length.
