The manuscripts are submitted by e-mail to the editor of the Editorial board of Yearbook Telecommunications (NBU, corpus 2, office 609, phone: 359 2 8110609, email: The manuscripts are in the .DOC(x) format, formatted according to the present Guidelines for sending manuscripts and using the template provided.

1.1. Schedule of publication and deadlines:

  • For handing over the manuscripts to the Editorial Board: currently, by 31 July of the current calendar year at the latest.
  • Review period - up to 2 weeks.
  • After receiving the remarks and the editor's notes and their removal, the author sends the corrected manuscript to the editorial board within 2 weeks by e-mail:

1.2. Reprint

The published manuscript includes a full bibliographic description of the source - title of the publication, e-mail address, ISSN, year, volume, start and end pages. This allows the author to use the article in pdf format as a complete reprint.

 1.3. Movement of manuscripts

 For each published manuscript, the movement of the manuscript is recorded - date of receipt, date of acceptance for publication.

1.4. Conditions for accepting manuscripts

(a) Manuscripts that are not designed according to these requirements or do not have the necessary qualities of reasonably well-documented research will not be published for which the authors will be notified.

  1. b) No work is accepted that copies lightly published articles of research, works with insufficiently substantiated claims, and works that are unreadable.
  2. c) The use of the subject-critical analysis-problem-goal-tasks-decision-conclusions-approach is recommended in the design of the manuscripts (the absence of such a scheme can significantly influence the reviewers' assessment).

It is recommended that the author, based on a critical review of the literature on the topic chosen, identify and point out the existing problems, requiring further research on the subject. Based on the critical analysis of the literature on the chosen topic, on the background of the existing one can be highlighted the new one, which is related to the author's name. Cursory scan of the Internet is not recommended.

1.5. Author's statement

 By sending a manuscript, the authors declare that:

  • the manuscript has not been published or made available for publication in other journals or forums;
  • are familiar with the publication requirements and the manuscript is prepared according to the Yearbook Telecommunications Submission Guidelines;
  • agree with the Copyright Terms stated in the Editorial Policy of Yearbook Telecommunications.

 1.6. Reviewing manuscripts received

 In order to evaluate the content of the manuscripts received, a Board of Reviewers has been set up at Yearbook Telecommunications. Board of Reviewers is periodically updated through a Call for Reviewers distributed among the experts deemed appropriate (at least with a PhD). Candidates for Reviewers in their Application Forms outline the limits of their scientific competence within selected scientific areas.

Two anonymous and independent reviewers do the evaluation of the content of the manuscripts through the "Blind Peer Review".

The manuscripts are submitted for review without information about the author(s) according to paragraph 2.5.

Each reviewer chooses one of the possible recommendations:

  • publish without change;
  • to be published after revision - the reviewer presents specific and detailed remarks to which the author has to respond and revise the manuscript (within the prescribed time frame) in accordance with the recommendations made;
  • Not to be published - if the Yearbook Telecommunications is not suitable for such a publication or if the manuscript does not contain well-grounded results.


 2.1. Rules for manuscript preparation

 It is recommended that a manuscript template be used ("ManuscriptTemplate"). The structure of manuscripts should be as follows:

  • title of the article and author's names (co-authors);
  • abstract;
  • keywords;
  • main text with built-in graphic materials (figures, charts, pictures, etc.), tables and formulas (if any); references (citations);
  • conclusion on the results obtained and relevant contributions;
  • a list of literary sources (References);
  • thanks (credits) - if any;
  • funding information (if any);
  • apps (if any);
  • contact information for each co-author.

 2.2. Structure of the manuscript

 Title. The title should summarize the paper’s main idea and identify the variables under discussion and the relationship between them. Avoid titles longer than 15 words.

Abstract. Concise and factual abstracts of 100 to 180 words are required for all manuscripts submitted. The abstract should state briefly the purpose of the research, the principal results and major conclusions. References, literature citations and abbreviations should be avoided.

Keywords. Immediately after the abstract, provide a maximum of 8 keywords, avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Keyword terms may differ from the actual text used in the title and abstract, but should accurately reflect what the article is about.

Section headings. Section headings should be concise.

Abbreviations. Abbreviations should be kept to a minimum and defined upon first use in the text. Non-standard abbreviations should not be used unless they appear at least three times in the text.

Footnotes. Footnotes in the manuscript should be used sparingly.

Author note template. An author note should appear as follows in a short narrative:

First sentence/paragraph: Degree(s), complete departmental and institutional affiliation, changes in affiliation (if any).

Second sentence/paragraph: Acknowledgments, funding sources, special circumstances.

Third sentence/paragraph: Research interests.

Fourth sentence/paragraph: Contact information (e-mail).

 2.3. Title page

 The Title page (saved as a separate file “TitlePage”) should include the following:

  • full article title;
  • acknowledgments and credits;
  • grant number(s) and/or funding information;
  • each author’s complete name and institutional affiliation(s);
  • a short biography (fewer than 100-150 words) for each author;
  • corresponding author (name, address, phone/fax, e-mail).

 Provide the author’s ORCiD ID for the corresponding author (mandatory) and for each author, if available. If you do not have one, you can register for free at

 According to volume guidelines, the authors include:

  • Number of words in the main text part of the manuscript =
  • Number of words in the rest of the text of the manuscript (review, critical analysis or comment) =

 2.4. Protocol-agreement between co-authors

 All persons who have a reasonable claim to authorship must be named in the manuscript as co-authors; the corresponding author must be authorized by all co-authors to act as an agent on their behalf in all matters pertaining to publication of the manuscript, and the order of names should be agreed by all authors. Also co-ordinated by all co-authors, it is necessary to indicate the percentage participation of each of them in the manuscript preparation.

The contents of the protocol-agreement between the co-authors may be as follows:

  • Title of the manuscript;
  • Authorized co-author and e-mail address;
  • Sequence of names in the manuscript and percentage of co-authorship (to be given in relation to the different parts / manuscript approaches such as: lead / supportive or equal participation);
  • Signatures of all co-authors and date.

The scanned protocol is sent as a separate file “Protocol”.

2.5. Blinded manuscript preparation guidelines

Due to the double anonymous review process, the co-authors must present two versions of the manuscript:

  • a manuscript submitted for publication (file „Manuscript“),
  • a manuscript submitted for review (file „BlindedManuscript“).

      As part of the blind peer review process, authors will need to upload a blinded manuscript without a title page (no author details), as well as a separate title page (containing author details). Blinded manuscripts should be compiled in the following order: full article title; abstract; keywords; main text with tables and embedded figures; references; appendices (as appropriate).

      Take the following steps to ensure the blinded manuscript (saved as a separate file “BlindedManuscript.doc(x)”) is correctly prepared for double-blind peer review:

       Remove names and affiliations under the title within the manuscript

       Remove names or other identifying information from the abstract

       Use the third person to refer to work the authors have previously undertaken, e.g. replace any phrases like “as we have shown before” with “… has been shown before [Anonymous, 2007]”.

       Make sure figures do not contain any affiliation related identifier

       Cite papers published by the author in the text as follows: ‘[Anonymous, 2007]’.

       For blinding in the reference list: ‘[Anonymous 2007] Details omitted for double-blind reviewing.’

       Remove references to funding sources

      Do not include acknowledgments

      Name your files with care and ensure document properties are also anonymized.
