异构携能通信网络中人工噪声辅助的顽健能量与信息安全传输方案
|
摘要
异构携能通信网络中CSI存在随机误差时,为保证信息与能量传输的安全性及可靠性,提出一种人工噪声辅助的顽健能量与信息安全传输方案。通过联合设计宏基站、微基站的下行信息波束矩阵及人工噪声矩阵,使网络中其他用户信号及人工噪声能够干扰窃听者。同时提升系统能量的接收性能。考虑CSI随机误差,在基站的发送功率约束、合法用户的信息接收中断约束及窃听者的信息窃听中断约束下,以最大化系统能量接收性能为目标进行数学建模。建模后的问题是非凸的,首先将其等效转化为一种易于处理的形式;然后,分别利用Berstein-type不等式和Large-deviation不等式这2种方式将其中的中断概率约束转化为凸的线性矩阵不等式;最后结合二次等式引理及递归估计算法处理秩为1波束成形约束的非凸性。仿真结果表明,与对比方案相比,所提方案具有更高的系统能量接收性能和可行解性能,验证了其有效性和顽健性。
A heterogeneous network with simultaneous wireless information and power transfer under the stochastic channel state information(CSI) error was considered. In this network, to guarantee the security and reliability of information and energy transmission, an artificial noise(AN)-aided robust secure information and power transmission scheme was proposed. By jointly designing the downlink information beamforming and AN matrix of macrocell base station and femtocell base stations, the eavesdroppers were jammed and the energy receiving performance of system was improved simultaneously. The problem of maximizing the energy receiving performance was modeled under the constraints on the base station power, the outage probability of information transfer and confidential information eavesdropped. Due to the probabilistic and rank-one constraints, this problem was non-convex. To obtain the solution, the original problem was first transformed into an equivalent form, which was easy to process. Then, the Bernstein-type inequality and the Large-deviation inequality was utilized to transform the outage probability limits into convex linear matrix inequalities,respectively. Finally, the rank-one beamforming constraints were processed with quadratic equality constraint procedure.Simulation results show that the proposed scheme has higher energy receiving performance and feasible performance in comparison with compared schemes, which validates the effectiveness and the robustness of our proposed scheme.
