We investigate how FEC (Forward Error Correction) can be combined with ARQ (Automatic Repeat Request) to achieve scalable reliable multicast transmission. We consider the two scen...
Convolutional spreading CDMA with cyclic prefix (CS-CDMA/CP) enables multiuser interference-free (MUI-free) transmission over multipath channels with the use of zero correlation zo...
Abstract. Mix networks are a popular mechanism for anonymous Internet communications. By routing IP traffic through an overlay chain of mixes, they aim to hide the relationship bet...
We continue our study of document marking to deter illicit dissemination. A n experiment we performed reveals that the distortion on the photocopy of a document is very different ...
