Investigation of parameters of models of acoustic echo-signals by method of correlation estimation

Methods Local Analysis and Processing of Acoustic Signals in the Diagnosis of Conditions Technical Systems and Telecommunications

“…This approach can be generalized by assuming that the finding is not subject to a discrete set of evaluation results or predictions, and a sequence of functions of a continuous argument, defined by a sequence of finite intervals, which are hereinafter referred to intervals of analysis. These functions include, in particular, is a generalization of polynomials (polynomials of a given system of basis functions) or the regression function obtained in the course of solving a sequence of least squares problems [3,4]. If, moreover, requires that the local evaluation results were represented generally smooth function that necessitates a smooth interfacing of said polynomials, the least squares problem is converted into a quadratic optimization problem with constraints in the general case, as the type of equality and inequality [4 -6].…”

On the Transmission of Asynchronous Data Streams Over Packet Switched Networks with Random Multiple Access

“…To account for the above equations in the automatic frequency unevenness forming the source sequence of data packets, application of adaptive control methods reference model [13,[15][16][17][18][19][20][21][22], which can be used as the above model of formation of the source data packets. In this case, instead of the frequency divider shown in Fig.…”
