Summary:The invention discloses a two-stage beam training method for a super-large-scale array communication system. In the first stage of beam training, each sub-array of the super-large-scale multiple-input-multiple-output system uses a series of far-field steering vectors to perform simulation merging. In a second stage of beam training, aiming at sight distance path channel estimation, firstly, a special digital combiner is designed for each codeword in a preset codebook; then, the digital processing unit uses a special digital combiner to carry out digital combination processing on the signals after the analog combination in the first stage. And finally, outputting the codeword capable of realizing the maximum combination power in the preset codebook as a beam training result. For multipath channel estimation, digital processing is carried out on signals after analog combination in the first stage of beam training to complete reconstruction of a channel transmission matrix. On the premise that the training overh
