Fig. 3From: Deep learning-based DOA estimation for hybrid massive MIMO receive array with overlapped subarraysThe procedure of proposed CDAE-DNN. This network is consisting of two parts, convolution denoise autoencoder (CDAE) and fully-connected deep neural network (DNN), the sample covariance matrix \(\tilde{\textbf{R}}\) is firstly input to CDAE, then the denoised covariance matrix \(\textbf{R}\) is sent to DNN for DOA estimationBack to article page
