In this work a new design procedure of approximately linear phase (ALP) digital Hilbert transformers (HT) is proposed. First, the possible positions of the transfer function (TF) poles of such HTs realizations are studied ...
The aim of this article is to suggest a way for adopting a strengthened risk management in the ITIL (Information Technology Infrastructure Library) framework which will be based on specific guidelines without changing the ...
Abstract: This paper presents and researches the application of miniaturized hexagonal resonators in microstrip bandpass filters in the mobile communication systems. There are investigated both basic topologies of miniaturized ...
In this paper are presented the results of a study of the characteristics of the DVB-S2 channels when using 32APSK and 64APSK modulation. Expressions for determining the probability of bit error after APSK demodulator, LDPC ...
In this paper the precision of variety direction of arrival (DOA) algorithms used in cognitive radio systems are investigated. The researched algorithms are MUSIC, Capon (MVDR), ROOT MUSIC, ESPRIT-LS and ESPRIT-TLS. The goal ...
The paper deals with signal degradation due to noise and nonlinear distortion in the forward channel of HFC television network. A mathematical model of the optical channel is presented that makes it possible for the following ...
