type="main" xml:id="jtsa12070-abs-0001"A two-step estimation method is proposed for periodic autoregressive parameters via residuals when the observations contain trend and periodic autoregressive time series. The oracle efficiency of the proposed Yule–Walker-type estimator is established. The...

A class of local correlation functions is obtained from B-spline bases and the corresponding stationary processes are constructed through local integration. Then a local Bayes estimate (LBE) is proposed using this process as a prior in a signal estimation problem. Mean square convergence of this...

In this paper, the authors propose an algorithm that increases and decreases the transmission speed according to a user-specified function. The design objective is to regulate baud as efficiently as possible and ensure that in each transmission interval, transmitter and receiver bauds are equal...
