Researchers propose a novel deep learning-based scheme for efficient OFDM channel estimation in wireless communication systems.
The scheme includes a dual-attention-aided super-resolution neural network (DA-SRNN) for channel reconstruction and continual learning (CL)-aided training strategies for generalization.
The DA-SRNN utilizes a channel-spatial attention mechanism and a lightweight super-resolution module.
The CL-aided training strategies help the neural network adapt to different channel distributions and improve performance.
