To solve the problem of high feedback overhead when the user sends channel state information (CSI) to the base station in massive multiple input multiple output (MIMO) based on Internet of things system. a CSI feedback network based on deep learning was proposed to feedback CSI. Firstly. the proposed network used convolutional neural network (CNN) to extract channel feature vectors an... https://parisnaturalfoodes.shop/product-category/herbatint-5m/
