Quality Performance of LD, SD and HD Video Encoded with Dirac and H.264/AVC
This paper compares the video quality performance of low definition (LD), standard definition (SD) and high definition (HD) video signals encoded with H.2...
Quantum Permanent Compromise Attack to Blum-Micali Pseudorandom Generator
This paper presents a quantum permanent compromise attack to the Blum-Micali pseudorandom generator whose security is based on the assumption of intractabil...
Reduced Complexity Viterbi Decoding Based on the M-Algorithm and the Minimal
In this paper we propose sub-optimum, reduced complexity decoding algorithms for convolutional codes. The algorithms are based on the minimal trellis repre...
