The Editor-in-Chief has retracted this article. Recently, a reader of Telecommunication Systems brought to our attention that some parts of this article [1] have been plagiarized from another publication [1] without giving a citation or credit. After investigating this case, it was confirmed that this paper duplicates Figs. 1, 2 and Tables 1, 2, and larger part of the text from [1]. Hence, the editorial team and publisher have determined that it should be retracted from the journal. The author disagrees with the retraction.

The online version of this article contains the full text of the retracted article as electronic supplementary material.
