Two-way wiretap channel secrecy rates are analyzed with artificial noise signal design and power allocation algorithms.
Sammanfattning
The content discusses the analysis of secrecy rates in a two-way wiretap channel with artificial noise signal design and power allocation algorithms. It explores scenarios with known and unknown factors affecting secrecy rates, including artificial noise allocation and partial precoder knowledge at Eve. The study provides insights into maximizing secrecy rates and improving system security.
Statistik
"Results show that secrecy rates are less when AN is unknown to receivers or Eve has more information about legitimate users."
"The power allocation problem is formulated to maximize sum ergodic rates, and a two-step solution is provided."
"Simulation verifies the usefulness of the power allocation to improve secrecy rates."
Citat
"The resulting power allocation provides secrecy rates close to the actual ones."
"The ergodic approximation only considers Eve’s distance."
