An intelligent impulsive noise mitigation with deep learning method
International Journal of Mechanical System Dynamics, Volume 4, Issue 3, Page 346-360, September 2024.Abstract To enable message transmission among sensors and equipment, power line communication (PLC) is a widely adopted smart grid. However, due to the occurrence of impulsive noise (IN), reliable transmissions over PLC channels in the smart grid are challenging.
