Telecommunication jitter measurement in the transmultipexer systems method based on the wavelet pattern correlation

Abstract

The paper presents a new method of the measure of the jitter in telecommunication. Jitter is the phenomenon which is especially harmful to the transmultiplexer systems, so its exact measure is very important to the system engineer. Described scheme is based on the recognition and correlation of the patterns generated by means of the wavelet transform. This research is a continuation of the work on development of the wavelet based jitter measurement methods that do not use the reference clock. Presented algorithm allows to estimate the jitter parameters in relation to the jitter wavelet base functions. Practical computer algorithm is also presented. Additionally, such topics like the wavelet type, its order, as well as calibrating methods are also discussed. This paper extends previous research and gives not only a proposal but also implementation details. © Springer-Verlag Berlin Heidelberg 2003.
