cardinal and concatenate

[lrfighting]

Hello, author, as shown in the figure, your paper concatenates multiple cardinal, but I can't find the concatenate code in your code, and I find cardinal = 1. Is it because cardinal = 1 that concatenate splicing is not required? Why do you set cardinal = 1?Thanks ！
