An FPGA-based (field-programmable gate array, FPGA) digital synchronization approach for merging unit (MU) was proposed, which included oversampling, linear phase-shifting, dynamic interpolation resampling technique.
Digital synchronization can overcome the failed attempts to realize experimentally a performed chaotic communication system.
For example, other than the analog processes (i.e., low-noise amplifier and ADC), the digital synchronization operation may even accounts for 30-40% energy consumption of receivers [37].
To demonstrate this capability, we created a program for our scan mirror hardware to use an external digital synchronization signal to trigger each x-axis scan, rather than to trigger each x-axis scan after each step of the y-axis.
The platform implements a microservice IoT-Big Data architecture supporting the distributed publication of multidisciplinary simulation models, managing in an optimized way streams of data coming from the shop-floor for real-digital synchronization, ensuring security and confidentiality of sensible data.
In the digital domain, synchronization problems exist due to data distribution and communications, random events caused by human computer interaction, and general computer and communications performance limitations.
To overcome these drawbacks, we propose in this paper a digital feedback hyperchaotic synchronization and suggest the use of advanced wireless communication technologies, characterized by high noise immunity, to exploit digital hyperchaotic modulation advantages for robust secure data transmissions.
Additionally, by applying anti-synchronization to communication systems, one may transmit digital signals by transforming between synchronization and anti-synchronization continuously, which will strengthen the security and secrecy.

The idea of registration (both spatial and temporal) is developed, especially as it is related with the alignment and synchronization of digital augmentations with the real world.
The engineering process of production systems is a cross-domain challenge between mechanics, electrics and software, but a lack of collaboration and universal information transfer between the domains leads to a high investment volume by synchronization the digital model from the time of commissioning.
