Dynamic Autoencoder‐Based Framework for Performance Enhancement in OFDM Systems Using CNN and Attention Mechanisms

ABSTRACT Traditional orthogonal frequency division multiplexing (OFDM) systems face significant performance degradation under dynamic channel conditions due to fixed channel estimation and static transmission parameters. Existing autoencoder‐based OFDM models improve end‐to‐end learning but lack adaptive mechanisms to handle varying SNR and multipath fading effectively. In this manuscript, dynamic autoencoder‐based framework for performance enhancement in OFDM systems using CNN and attention mechanisms (DAF‐OFDM‐CNN) is proposed. This paper proposes a dynamic autoencoder‐based framework to enhance the performance and reliability of OFDM systems under fluctuating signal‐to‐noise ratio (SNR) conditions. The framework integrates convolutional neural networks (CNN) and an attention mechanism within autoencoder architecture to improve feature extraction, channel estimation, and adaptive transmission. The system dynamically prioritizes important signal features, enabling effective data recovery and robust communication in multipath fading environments. Simulation results demonstrate that the proposed model significantly improves error rates, throughput, and latency compared to conventional OFDM systems, confirming its potential for next‐generation wireless communication networks.
