Dalam makalah ini, teknik penapisan takuk adaptif berasaskan kumulan baru untuk peningkatan dan pengesanan sinusoid tunggal dalam hingar aditif dibentangkan. Dalam teknik ini, isyarat yang dipertingkatkan diperolehi sebagai output penapis laluan jalur sempit yang dilaksanakan menggunakan penapis takik penyesuaian IIR kekangan kutub sifar tertib kedua, yang memerlukan hanya satu pekali untuk dikemas kini. Pekali penapis, yang membawa kepada mengenal pasti dan menjejaki frekuensi sinusoidal, dikemas kini menggunakan algoritma penyesuaian yang dicadangkan menggunakan anggaran rekursif bagi kurtosis dan hanya satu titik lag sampel bagi hirisan kumulan terkumpul tertib empat satu dimensi terpilih bagi input isyarat. Oleh itu, teknik yang dicadangkan memberikan rintangan secara automatik kepada bunyi Gaussian aditif. Ia juga menunjukkan bahawa teknik yang dibentangkan mengatasi rakan sejawat berasaskan korelasi dalam mengendalikan bunyi aditif bukan Gaussian. Keputusan simulasi disediakan untuk menunjukkan keberkesanan algoritma yang dicadangkan berbanding dengan algoritma kekisi berasaskan korelasi.

Abstract: In this paper, a novel cumulant-based adaptive notch filtering technique for the enhancement and tracking of a single sinusoid in additive noise is presented. In this technique, the enhanced signal is obtained as the output of a narrow bandpass filter implemented using a second-order pole-zero constraint IIR adaptive notch filter, which needs only one coefficient to be updated. The filter coefficient, which leads to identifying and tracking the sinusoidal frequency, is updated using a suggested adaptive algorithm employing a recursive estimate of the kurtosis and only one-sample-lag point of a selected one-dimensional fourth-order cumulant slice of the input signal. Therefore, the proposed technique provides automatically resistance to additive Gaussian noise. It is also shown that the presented technique outperforms the correlation-based counterpart in handling additive non-Gaussian noise. Simulation results are provided to show the effectiveness of the proposed algorithm in comparison with the correlation-based lattice algorithm.
