Problems solved by technology

However, in some communication scenarios, the distribution of noise and interference is very complex, it is not easy to analyze and deal with, or it is difficult to find a model suitable for describing its distribution
In this case, traditional model-based detectors do not work well, which makes it urgent for us to study a new type of detector that can adapt to communication scenarios affected by complex noise or interference

Abstract

The invention discloses an iterative intelligent signal detection method based on a neural network, and the method comprises the following steps: 1, inputting a to-be-detected signal to a signal detector, and obtaining an interference signal estimation value; 2, inputting the interference signal estimation value into a deep neural network to obtain the to-be-detected signal; and step 3, repeatingthe step 1 and the step 2 for several times, and outputting a final signal by the signal detector. The invention further provides an iterative intelligent signal detection device and equipment based on the neural network, and a storage medium. By adopting the method and the device, the signal detection performance in a scene subjected to complex dynamic related interference can be improved.

Description

technical field [0001] The invention relates to the field of signal detection, in particular to an iterative intelligent signal detection method based on a neural network. Background technique [0002] The multiple-input multiple-output (MIMO) communication system has the advantage of space diversity and can effectively meet the high data volume requirements of the next generation communication network. For existing traditional detectors such as maximum likelihood detector (MLD), minimum mean square error detector (MMSE) and zero-forcing detector (ZF), most of the detection algorithms used are based on a specific A mathematical model whose theoretical assumptions require knowledge of the specific distribution of noise or interference. However, in some communication scenarios, the distribution of noise and interference is very complex, which is not easy to analyze and deal with, or it is difficult to find a model suitable for describing its distribution. In this case, tradi...
