implementation of research paper Federated Learning for Channel Estimation in Conventional and RIS-Assisted Massive MIMO

Implementing the research paper "Federated Learning for Channel Estimation in Conventional and RIS-Assisted Massive MIMO" with the desired outcome of improving channel estimation accuracy. I am looking for an expert in Federated Learning and RIS-assisted Massive MIMO with a strong understanding of the concepts involved. The implementation should be done using Python.
