I tried downloading this paper https://ieeexplore.ieee.org/document/9526393[https://ieeexplore.ieee.org/document/9526393](https://ieeexplore.ieee.org/document/9526393) from scihub…but it shows the article is not found. I tried using my college access, but it’s outside my organization’s subscription seems. Can anyone help me download this paper? It would be of great help.
