Imperfect channel
Witryna10 sie 2024 · Under the practical assumption of imperfect channel state information (ICSI) for the relay-to-receiver D2D link, we take into account optimal power allocation (OPA) problem to maximize the achievable secrecy rate of two different scenarios which are without jamming and with friendly jamming. WitrynaIn this special presentation, renowned research professor and author Dr. Brené Brown shares what she's learned from a decade of research on the power of auth...
