Abstract EN
The physical layer security of downlink nonorthogonal multiple access (NOMA) network is analyzed.
In order to improve the secrecy probability, friendly jammers are jointed in the NOMA network.
Two jammer schemes are proposed in the NOMA network.
All the jammers transmit jamming signal without jammer selection in the first scheme (NO JS scheme).
Jammers are selected to transmit jamming signal if their interfering power on scheduled users is below a threshold in the second scheme (JS scheme).
A stochastic geometry approach is applied to analyze the outage probability and the secrecy probability.
Compared with the NO JS scheme and traditional scheme (without jointing jammers), the jammer selection scheme provides a good balance between the user outage probability and secrecy probability.
Numerical results demonstrate that the security performance of the two proposed schemes can be improved by jointing the jammers in the NOMA wireless network.
