Abstract: Let {εt;t∈Z+} be a strictly stationary sequence of LPQD random variables with mean zeros, let 021<∞,with 0<σ2<∞, {j;; j∈N } is a sequence of real numbers satisfying. Define a linear process Xt. In this article, by means of the weak convergence theorems and moment inequalities, the precise asymptotics of {Mn} and {Sn}is proved for more general weighted functions and boundary functions.
