Discrete-Time Biomedical Signal Encryption
Journal Title: Memoirs of the Scientific Sections - Year 2017, Vol 0, Issue
Abstract
Chaotic modulation is a strong method of improving communication security. Analog and discrete chaotic systems are presented in actual literature. Due to the expansion of digital communication, discrete-time systems become more efficient and closer to actual technology. The present contribution offers an in-depth analysis of the effects chaos encryption produce on 1D and 2D biomedical signals. The performed simulations show that modulating signals are precisely recovered by the synchronizing receiver if discrete systems are digitally implemented and the coefficients precisely correspond. Channel noise is also applied and its effects on biomedical signal demodulation are highlighted.

On the Anisotropy of Images. A Brief Note
Many physical systems, known as highly dependent on direction, are called anisotropic. Anisotropy is characterized by different properties, measured along each axis in different directions. For understanding physical phe...
