Frequency Estimation Based on SNR-adaptive Frequency Estimator Under Wide SNR Range
SAFE consists of a time-frequency image neural network, which enhances weak tone frequency components at low SNR, and an SNR-based frequency selector, which selects an appropriate frequency estimator according to the SNR of the estimated tone frequencies, enabling SAFE to achieve robustness at low SNR while preserving...
