Computational imaging method based on cellular-free large-scale MIMO (Multiple Input Multiple Output) system

The invention discloses a computational imaging method based on a cellular-free large-scale MIMO (Multiple Input Multiple Output) system. In a cellular-free large-scale MIMO system, a plurality of access points are connected to a central processing unit in a wireless or wired manner, and target imaging is realized by using wireless signals from a plurality of devices. In order to recover an interested target object in the environment, a plurality of pieces of user equipment emit sensing signals at the same time, the sensing signals are scattered by the target object and then reach each access point, and the access points calculate the signals received by the access points respectively to obtain a local initial object image. And then the access point transmits the initial image data to the central processing unit for fusion processing, thereby realizing accurate imaging of the target object. The invention provides a simple and effective computational imaging method for accurate imaging of an interested target
