Research on Digital Steganography and Image Synthesis Model Based on Improved Wavelet Neural Network. [PDF]

Comput Intell Neurosci, 2022
Network compression coding technology is a research hotspot in the field of digital steganography and image synthesis. How to improve image quality while achieving short compression time is a problem currently faced. Based on the improved wavelet neural network theory, this paper constructs a digital steganography and image synthesis model.

Symbol interferometry and companding transform for PAPR reduction of OTFS signal

ETRI Journal
This paper presents methods for reducing the peak-to-average power ratio (PAPR) of the orthogonal time frequency space (OTFS) signal. These methods mainly consist of two operations: symbol interferometry (SI) and either μ-law or A-law companding.
