Hidden transmission strategy of NOMA-RIS-assisted communication and inductance integrated system

The invention relates to a hidden transmission strategy of a communication and inductance integrated system based on NOMA-RIS assistance. The hidden transmission strategy comprises the following steps: establishing a total transmission model; the total transmission model comprises a system model, a communication model, a radar detection model and a covert communication model; the system model comprises DFBS, RIS, a target, a public user, a hidden user and an eavesdropper; checking whether the CSI acquired by the DFBS is the perfect CSI of the eavesdropper or the imperfect CSI of the eavesdropper; if the DFBS obtains the perfect CSI of the eavesdropper, executing a first hidden transmission strategy; and if the DFBS obtains the imperfect CSI of the eavesdropper, executing a second hidden transmission strategy. According to the method, the proposed optimization problem is efficiently optimized; coupling variables and complex constraints are processed more flexibly, the convergence and efficiency of the algorith
