and shorter hop length or proper power allocation for secret data and AN can mitigate the negative impact of frequency deviation, which in turn guides the practical transceiver design.

In the fast-paced evolution of data centers, the spotlight on sustainability has never been brighter. As energy demands surge ...

Abstract: Line-of-sight free-space optical links can provide extremely high bandwidth communications, but this usually requires that transmitter and receiver are precisely aligned. In order to allow ...
