摘要：
To solve the information security issue in the multiple input single output (MISO) simultaneous wireless information and power transfer (SWIPT) system, an artificial noise (AN)-aided beamforming scheme is proposed, and further formulating the problem as a power control problem under user requirement constraint. However, this problem is of huge non-convex complexity and cannot be solved in polynomial time. Therefore, an efficient two-tier algorithm is developed for a sub-optimal solution, which is extended further to the imperfect channel conditions for a robust beamforming scheme. Simulation results show that the two-tier algorithm has better performance and more robustness when compared with the classic zero-forcing (ZF) algorithm, and the advantage of it is more obvious as the channel estimation error increases. © 2021, Editorial Office of Systems Engineering and Electronics.
