Open Access Policy


A preprint is an early version of an article prior to the version accepted for publication in a journal. This journal allows preprints to be posted anywhere at any time, including before submission to the journal. For more information, see our full preprint policy.

Open Access

This journal is a wholly Open Access journal. It provides authors with options to make their article open access in two different ways.

(1) All articles are published as Gold Open Access under a Creative Commons license, enabling anyone to access and redistribute the content and, depending upon the license, re-use the content in new or derivative works with attribution. The terms of re-use for Gold Open Access content are stated in the copyright line.

Gold Open Access is supported by an article processing charge (APC) typically paid by the author’s funding body or institution.

Find the APC for this journal in our full list of APC charges.

We have made a number of Read and Publish agreements to support Open Access. Authors at participating institutions may be eligible for waivers or discounts, depending on the deal. Please click here to find out more.

 (2) Under the journal’s Green Open Access policy, authors can archive a pre-final version of their article in institutional or non-commercial subject repositories, or on their personal or departmental websites, under certain conditions. This allows authors to comply with the open access mandates of many funders and institutions before the final article is published as Gold Open Access.

For more details, see the journal’s full policy.

Social Sharing

Journals participating in Cambridge Core Share allow a read-only version of a final published PDF (the Version of Record) to be shared and easily accessed by anyone. Core Share links, and Core Share PDFs containing the links, can be freely shared on social media sites and scholarly collaboration networks to enhance both the impact and discoverability of research. Core Share can be useful for articles that are published under a Creative Commons license that does not allow commercial re-use (such as CC-BY-NC-ND).

Open Access is the practice of making published research freely accessible to all. Whilst there are a number of mechanisms for making this content freely available, the Gold open access model used by APSIPA Transactions on Signal and Information Processing requires that the published 'version of record' be made freely available to all immediately upon publication, with additional usage rights. As no subscriptions are sold to view the content, such open access journals are typically financially supported through an article processing charge (APC) levied on the submitting author's institution or funding body.

Benefits of open access with APSIPA Transactions on Signal and Information Processing

  • Visibility: Articles are freely available online immediately upon publication, giving the potential for increased exposure and dissemination.
  • Accessibility: Gold open access allows all readers with internet access around the world to access published research without having to pay for a subscription.
  • Quality: All submissions will be fully peer-reviewed, with acceptance decisions being made by an international Editorial Board independently of the Publisher.

There are many stakeholders in the publication of research: the researchers, the users and the funders. Different stakeholders have different views but many accept the fact that if you want, for example, validation, proper copyediting, presentation, sustainability, functionality (usability, reference linking, usage information, discoverability, etc), then all this has to be paid for. Traditionally this payment has been made via subscriptions. In open access publishing, the payment is made up-front, via article processing charges (APCs). APCs can be seen as a fairer payment mechanism, provided that the costs on which the charges are based reflect accurately the services offered, and provided that the acceptance process is based on peer review, rather than financial considerations.

Open access can therefore provide an opportunity to relate costs more directly to the means of publication, and it can provide a mechanism for publication that preserves the best aspects of traditional publishing whilst offering greater ease of use and more liberal copyright and ownership. Moreover, APCs mean that costs are not being met by an ever-decreasing number of libraries that are willing to subscribe, and that the costs of publication are therefore being shared more fairly, while at the same time maximizing dissemination.

Finally, publishing is competitive: authors compete for journal space, publishers compete for papers and for library budgets. Open access and APCs are a viable alternative for those authors who want to bring closer together the decisions about where to publish and how to pay, decisions that are divorced in the traditional subscription-based model.

Publication charges Open Access publishing in ###em is funded through levying an article processing charge (APC) on each individual author's institution or funding body. There are no extra submission or figure charges. For APSIPA Transactions on Signal and Information Processing we are committed to maintaining the APC at a level justified by real publishing costs, and the journal will have an associated APC of £435 per article (in 2020).

Cambridge University Press operates waiver policies and meet the publications costs for those authors who require support in paying publication costs.

Developing country waiver policy

Cambridge University Press operates waiver policies in line with other leading publishers. We grant 100% waivers to papers whose corresponding authors are based in ###a href="" target="_blank">Research4Life 'Group A' countries and 50% waivers to those who are based in 'Group B' countries.

Discretionary waiver policy

  1. (i) The author(s) must request a waiver at or before submission, before an article enters editorial consideration by contacting
  2. (ii) The author(s) must provide documentary evidence for their request.
  3. (iii) The waiver request should be processed by the managing editor, without the knowledge of the editorial board.
  4. (iv) The waiver request should be processed as quickly as possible before the article moves from submission to editorial consideration
  5. (v) The decision to approve or decline the waiver request should be based on the credibility of the evidence the author provides and the author following the journal's waiver request procedure.

Read and Publish deal authors

Information regarding Cambridge University Press Open Access Read & Publish deals can be found here. See if your institute already has an agreement with the Press.

Editorial waiver policy

Waivers will be automatically granted for all:

  • Editorials
  • Errata/corrigenda

Full waivers will automatically be granted via RightsLink.

The decision whether to accept a paper for publication will rest solely with the Editors, and without reference to the funding situation of the authors. The Editors, editorial board members, and reviewers will have no involvement with the billing of APCs and cannot grant waivers.

In the appropriate cases, the publication charge will be billed on acceptance of the article for publication.

Copyright Information

The author will retain the copyright of published articles.

Authors will be able to post the final published version of their article anywhere (e.g. personal webpage, institutional repository), providing the work is fully attributed. We note, however, that we can currently only track usage statistics for article views and downloads from our own site.


Articles will be published, by default, under a creative commons attribution licence (CC-BY). Authors will, however, have the option to publish under a CC-BY Non-Commercial Share Alike (CC-BY-NC-SA) licence or a CC-BY Non-Commercial No Derivatives (CC-BY-NC-ND) licence if so desired.
