This invention discloses a method for optimizing the neutral rate in an MA-assisted RSMA-RIS system. The method first presents an algorithm for updating the position of the movable antenna (MA), and then provides an algorithm for obtaining the optimal system neutral rate based on AO iteration. This invention can solve the problems of precoding design, antenna position, RIS reflection matrix design, and common rate partitioning scheme design in MA-assisted multi-user downlink RSMA-RIS systems. It obtains the optimal solution for the system neutral rate through iteration and can quickly converge to the optimal solution.

The application provides a distributed RIS cooperation channel estimation and interference management method and system, and belongs to the technical field of channel estimation and interference management. The application combines a distributed timing pilot architecture, a history data driven minimum mean square error Wiener filter interpolation technology based on strict causality, a weighted minimum mean square error iterative collaborative optimization algorithm using spatial diversity, and a Kalman filter algorithm prediction closed-loop control mechanism assisted by a deep learning neural network. Especially for a super large scale multiple input multiple output system, the application can adaptively process the spatial non-stationary characteristics of the array in channel estimation and beamforming optimization, and realizes joint resolution enhancement in the angle domain and the distance domain based on a near-field spherical wave channel model, thereby providing a set of logically rigorous, mathematically complete and engineering implementable channel acquisition and interference management overall patent solution for future 6G large-scale network deployment.
