New Guess-and-Determine Attack on the Self-Shrinking Generator
We propose a new type of guess-and-determine attack on the self-shrinking generator (SSG). The inherent flexibility of the new attack enables us to deal with different attack condi...

Low complexity H.263 to H.264 video transcoding using motion vector decomposition
The H.264 adopts various block types and multiple reference frames for motion compensation. For transcoding a video sequence from the H.263 format to the H.264 format, it is benef...

Feedback Capacity of the Gaussian Interference Channel to within 2 Bits
We characterize the capacity region to within 2 bits/s/Hz and the symmetric capacity to within 1 bit/s/Hz for the two-user Gaussian interference channel (IC) with feedback. We dev...
