We ask that you refrain from uploading already copyrighted material, such as the published version of your paper; instead, you may upload manuscripts/pre-prints, and If your paper is published, provide a link in the document description/abstract field to the publisher’s website through which a final version can be found (for example, this can be a DOI link that would lead to your paper on the IEEE Xplorer). It's the uploader's responsibility to manage copyright issues. SigPort retains the right to remove copyrighted material and inappropriate content that are brought to the SigPort's attention. No refunds will be given to the uploading users in these cases.
