Statistical Attack Resilient Data Hiding
In this paper, we propose a discrete cosine transform (DCT) based spread spectrum data-hiding algorithm that is resilient to statistical attacks. Unlike other spread spectrum base...

Bit-Interleaved Coded Modulation with Mismatched Decoding Metrics
Bit-interleaved coded modulation (BICM) has become the de facto coding standard for communication systems. Recently, BICM has been cast as a mismatched decoding scheme due to the ...

Improved audio coding using a psychoacoustic model based on a cochlear filter bank
Perceptual audio coders use an estimated masked threshold for the determination of the maximum permissible just-inaudible noise level introduced by quantization. This estimate is d...
