Abstract： Extremely massive multiple input multiple output(MIMO) has shown considerable potential in future mobile communications. However, the use of extremely massive aperture arrays will lead to spatial non-stationary channel conditions，and each antenna of the base station is equipped with a high-precision quantizer, the power consumption of the system will be greatly increased, which will hinder the widespread application of ultra-large-scale MIMO systems. Therefore, this article assumes that each antenna of the base station is equipped with a pair of 1-bit analog-to-digital converters(ADC), and uses the mapping relationship between the sub-array and the user to describe the non-stationary channel characteristics. Based on the powerful generalization ability of neural network(DNN), this paper designs a new generative supervised DNN model that can be trained with a reasonable number of pilots. The simulation results show that the proposed network can achieve better estimation performance with less pilots and achieve a good balance between performance and complexity.
