Abstract: Embodiments of the present application provide a signal detection method and a related device, used for optimizing a processing process of bit soft information estimation, and improving communication efficiency. In the method, a statistical feature of a signal to be detected can be processed by using a neural network, and corresponding bit soft information can then be output; a comparison operation in a conventional max-log algorithm is replaced with a multiply–accumulate operation which is more universal and efficient in a neural network processing process. In addition, in the method, a sampling result for indicating discrete information of a posterior probability of the signal to be detected can also be obtained by means of randomly sampling a received signal according to a filtering parameter of the received signal; compared with an implementation process of participating in calculation by means of multiple QR decompositions, random sampling can reduce the complexity of the calculation process. Thus, a signal processing process of a signal detection apparatus is optimized, and the communication efficiency is improved.
