چکیده
A new algorithm based on the combination of chaotic sequences and immune differencing is proposed to improve population diversity capability in order conventional for solving signal-to-noise optimal problem. The method uses sequence expansion, accuracy analysed. In test effectiveness algorithm, it applied a function optimisation Simulation results show that has lower number iterations better accuracy.

Improvement of signal-to-noise ratio in chaotic laser radar based on algorithm implementation
Chaotic laser radar based on correlation detection is a high-resolution measurement tool for remotely monitoring targets or objects. However, its effective range is often limited by the side-lobe noise of correlation trace, which is always increased by the randomness of the chaotic signal itself and other transmission channel noises or interferences. The experimental result indicates that the w...

Effect of signal to noise ratio on the speech perception ability of older adults
Background: Speech perception ability depends on auditory and extra-auditory elements. The signal-to-noise ratio (SNR) is an extra-auditory element that has an effect on the ability to normally follow speech and maintain a conversation. Speech in noise perception difficulty is a common complaint of the elderly. In this study, the importance of SNR magnitude as an extra-auditory effect on speech...
متن کاملTrajectory optimization based on the signal-to-noise ratio for spatial encoding with nonlinear encoding fields.
PURPOSE Multiple nonlinear gradient fields offer many potential benefits for spatial encoding including reduced acquisition time, fewer artefacts and region-specific imaging, although designing a suitable trajectory for such a setup is difficult. This work aims to optimize encoding trajectories for multiple nonlinear gradient fields based on the image signal-to-noise ratio. THEORY AND METHODS...
متن کاملA Novel Restoration Algorithm Based on Optical Signal-to-Noise Ratio for Transparent Optical Networks
In this paper, we propose a novel algorithm to restore calls upon a single failure in transparent optical networks. After a failure, the proposed algorithm performs a path restoration searching for the route which presents the higher optical signal-to-noise ratio. We compared our proposal to three other well known approaches in the literature. We achieved lower failure rates in the restoration ...
