Leveraging LSTM Networks for CFO Estimation in MIMO-OFDM System Optimization

This paper presents a novel method for determining carrier frequency offset and lowering inter-carrier interference in MIMO-OFDM systems using Long Short-Term Memory Networks. The suggested approach calculates the Carrier Frequency Offset (CFO) and reduces Inter-Carrier Interference (ICI) in MIMO-OFDM systems using Long Short-Term Memory Networks. We derive the performance measures from the simulation data and develop the approach equations for the proposed strategy. In terms of Bit Error Rate (BER), Mean Square Error (MSE), and Mean Absolute Error (MAE), the proposed approach outperforms conventional methods. 5G and 6G networks are the best examples of the many wireless communication technologies that can profit from the recommended strategy.
