摘要:

针对双可重构智能表面(RIS)辅助的无线通信系统,提出了基于主被动波束成形联合优化的抗干扰通信方法。以接收信干噪比最大化为目标,构建主被动波束成形的联合优化问题。基于交替优化算法,将联合优化问题分解为3个子问题来迭代求解。通过半定松弛算法求解各RIS的近似最优被动反射向量;基于广义瑞利商求解基站的最优主动波束成形向量。仿真结果表明,所提方法优于传统的单RIS辅助抗干扰通信方法。

Abstract:

For double-reconfigurable intelligent surface (RIS) assisted wireless communication system, an anti-jamming communication method based on joint active and passive beamforming optimization was proposed.In order to maximize the received signal-to-interference-and-noise ratio (SINR), a joint active and passive beamforming optimization problem was formulated.By using the alternating optimization (AO) algorithm, the formulated joint optimization problem was divided into three subproblems, which were solved iteratively in an alternating manner.Specifically, the quasi-optimal passive beamforming vector of each RIS was obtained by applying the semidefinite relaxation (SDR) algorithm, and the optimal active beamforming vector of the BS was obtained based on the generalized Rayleigh quotient.Simulation results demonstrate that the proposed method outperforms the traditional single-RIS ant-jamming communication methods.

Key words: reconfigurable intelligent surface, anti-jamming communication, beamforming, alternating optimization
