4. 8. Modulation for interference avoidance on the AWGN channel

   University essay from KTH/Kommunikationsteori

   Author : Jinfeng Du; [2006]
   Keywords : Costa precoding; dirty paper coding; interference avoidance; Tomlinson-Harashima precoding;

   Abstract : Theoretic results have shown that the capacity of a channel does not decrease if the receiver observes the transmitted signal in the presence of interference, provided that the transmitter knows this interference non-causally. That is, if the transmitter has non-causal access to the interference, by using proper precoding this interference could be “avoided” (as if it were not present) under the same transmit power constraint.

6. 10. Implementation of a Watermarking Algorithm for H.264 Video Sequences

   University essay from Institutionen för systemteknik

   Author : David Bergkvist; [2004]
   Keywords : Technology; watermark; fingerprinting; image coding; TEKNIKVETENSKAP;

   Abstract : In today's video delivery and broadcast networks, issues of copyright protection have become more urgent than in analog times, since the copying of digital video does not result in the decrease in quality that occurs when analog video is copied. One method of copyright protection is to embed a digital code, a"watermark", into the video sequence. READ MORE
