Signal detection method and apparatus

Abstract

The present disclosure provides signal detection methods and apparatuses. A method executed by a network side device includes: obtaining a channel matrix by performing a channel estimation on a signal received from a terminal device; performing a data preprocessing on the channel matrix to obtain a first matrix and a first vector; and inputting the first matrix and the first vector into a trained deep learning model to obtain an estimated detection signal, wherein the trained deep learning model includes N trained convolutional network models, and N is a positive integer equal to a number of transmitting antennas.
