主　　题：radio map deep learning MIMO taskoriented approach 

摘      要：Radio map is an advanced technology that mitigates the reliance of multiple-input multiple-output(MIMO)beamforming on channel state information(CSI).In this paper,we introduce the concept of deep learning-based radio map,which is designed to be generated directly from the raw CSI *** accordance with the conventional CSI acquisition mechanism of MIMO,we first introduce two baseline schemes of radio map,i.e.,CSI prediction-based radio map and throughput predictionbased radio *** fully leverage the powerful inference capability of deep neural networks,we further propose the end-to-end structure that outputs the beamforming vector directly from the location *** rationale behind the proposed end-to-end structure is to design the neural network using a task-oriented approach,which is achieved by customizing the loss function that quantifies the communication *** results show the superiority of the task-oriented design and confirm the potential of deep learning-based radio map in replacing CSI with location information.
