MIMO system-based signal detection method and device, and storage medium

A non-transitory computer storage medium, which is configured to store computer-executable instructions for executing signal detection method based on a MIMO, wherein the signal detection method comprises:

• performing a scaling calculation on a first covariance matrix according to first main diagonal elements in the first covariance matrix to obtain a second covariance matrix;
• obtaining a whitening matrix according to the second covariance matrix;
• taking the whitening matrix, a vector of a receiving signal and a channel matrix as input parameters, and inputting the input parameters into a mathematical model for a whitening operation and perform a whitening calculation to obtain an operation result;
• and
• detecting a transmit signal in the MIMO system according to the operation result to obtain a detection result.
