This paper discusses the structure and properties of spectrum support for plateaued functions .We give the relation-ship between the set of rth-order plateaued functions’ all nonzero walsh spectrum points and the dimension of linear structure set . Meanwhile ,we utilize spectrum index to analyze the autocorrelation properties of both second-order and 4th-order plateaued func-tions .And the distribution of their autocorrelation coefficient is given .Moreover ,we talk about the structure characteristics of rth-or-der plateaued functions’ spectrum support and zero walsh spectrum points set .We present the relationship among their autocorrela-tion coefficients and point out the relationship between the spectrum support and the balance property when more rth-order plateaued functions’ spectrum supports are not cross .
