Abstract(in English) In this paper, we propose a memory driven simple transformer (MDST) deep learning (DL) model with the autoregressive module and spatial attention method, and channel matrix compression method to realize the high accuracy with small data collecting and low training overhead for intelligent reflecting surface (IRS)-assisted millimeter wave (mmWave) wireless communication system. Specifically, in the channel matrix compression, we convert the channel state information (CSI) into the sparse angular-delay domain, then the data size is significantly compressed in the delay domain. In the MDST-DL model, first, compressed CSI is input to the gated recurrent unit (GRU) to extract the frequency features. After that, these frequency features are input to the simple spatial attention to obtain the global features based on the frequency features extracted from each element. As the results show, in the case of compressed channel, the MDST-DL model can achieve the sufficient average accuracy of 80.0% with 17min 12s in comparison with the average accuracy of original channel of 85.7% with 22min 10s.
