Aiming at multisection sinusoidal signals with the same frequency and length, a frequency estimation algorithm of multisection signals with the same frequency and length based on spectrum correlation is proposed. It can improve the frequency estimation precision of short-time sinusoidal signal under the condition of low SNR. Firstly, generate a spectrum zoom sequence and calculate the spectra of corresponding...
Based on spectrum correlation of Multi-section Sinusoids with the Known Frequency-Ratio (hereinafter referred as MSKFR), a frequency estimation algorithm was proposed. This algorithm aims at improving frequency estimation of the short sinusoid at low Signal-to-Noise Ratio(SNR), and extending the applicable range of the multi-section signals fusion method. Firstly, an easy way to get MSKFR in application...
