- W2352604246 abstract "A secure communication scheme based on artificial noise assisted from base station(BS) was proposed to improve the system secrecy rate of the D2 D underlaying cellular. Firstly, the system secrecy rate was modeled. Then the BS with multi-antennas added artificial noise(AN) in cellular user's signal as well as designed beam vectors of the desired signal and artificial noise to maximize system secrecy rate. In the end, a joint optimization scheme based on the fairness constraint was introduced to optimize beam vectors of the desired signal, the power allocation for BS's information signal and AN and the D2 D power control. Simulation results show that the system ergodic secrecy rate can be improved 2.7 bit·s-1·Hz-1 more than the schemes based on SVD and zero-forcing at most." @default.
