Secrecy capacity and optimal time allocation for MISO wiretap channel with a multiple-antennas jammer
Electronics Letters(2020)
摘要
A closed-form expression of the achievable secrecy rate is derived in this study, which is used as the objective function to find the optimal time allocation of channel estimation and transmission. Theory analysis and numerical results demonstrate that the maximum secrecy capacity depends on the total time budget as well as the power at the transmitter.
