Abstract
Estimation of instantaneous frequency of narrowband com- plex sinusoids is often performed using lightweight algo- rithms called adaptive notch filters. However, to reach high performance, these algorithms require careful tuning. The paper proposes a novel self-tuning layer for a recently intr o- ducedadaptive notch filtering algorithm. Analysis shows th at, under Gaussian random-walk type assumptions, the resultin g solution converges in mean to the optimal frequency estima- tor. A simplified one degree of freedom version of the filter, recommended for practical applications, is also proposed. Fi- nally, a comparison of performance with six other state of th e art schemes is performed. It confirms the improved tracking accuracy of the proposed scheme
