Statistical characterization of the signal-to-noise ratio (SNR) reconfigurable intelligent surface (RIS)-assisted communications in presence phase noise is an important open issue. In this letter, we exploit concept copula modeling to capture non-standard dependence features that appear due discrete noise. particular, consider outage probability RIS systems Rayleigh fading channels and provide ...

This paper studies one typical mobile edge computing (MEC) system, where a single user has some intensively calculating tasks to be computed by M nodes (ENs) with much more powerful capability. In particular, unmanned aerial vehicle (UAV) can act as the ENs due its flexibility and high mobility in deployment. For this we propose several EN selection criteria improve system whole performance of ...

The amount of sensitive data, which is transmitted wirelessly will increase with future technologies. This raises many questions about secure data transmission. Besides cryptography, information-theoretic security gained increasing attention over the recent years. Among others, it deals problem transmission on physical layer to a legitimate receiver (Bob) in presence an eavesdropper (Eve). In t...
