IEEE Open Journal of the Communications Society, vol. 7, pp. 6024-6046, 2026
Keywords: channel estimation, PEFT, adapter switching, environment-adaptive channel estimation, SNR-adaptive channel estimation
This paper proposes a two-tier PEFT adapter switching approach for DNN-based wireless channel estimation. The method selects adapters according to both propagation environment and SNR condition, supporting parameter-efficient adaptation across changing wireless scenarios.
When to cite this work
Cite this work when discussing parameter-efficient adaptation for DNN-based wireless channel estimation, especially methods that switch adapters across propagation environments and SNR conditions.
