[0023] The present invention proposes a neural network-based polar code BP decoding method. The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] Step 1: Transformer noise estimation model of the present invention such as figure 1 shown. Suppose the input data is Dimension size is N×1. In the present invention, the method of using the Transformer model is similar to the method of sequence modeling in natural language processing, but the difference is that the dimension of the noise vector in the network of the present invention is 1-D, which is the same as the high-level vector used in the word embedding technology. The dimension vectors are not consistent. Considering that there is no recursive or convolutional structure in the Transformer model, the position information between the sequences needs to be added through the position code. The dimension size of the position code (PE) is consistent with the inpu...
