Double-RIS assisted anti-jamming communication method based on joint active and passive beamforming optimization
Published 2022-07-01“…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.…”
