Estimation in Frequencies of Multiple Sinusoids by the Modified ESPRIT Method

수정된 ESPRIT 방법을 이용한 다단 정현파의 주파수 추정

The modified ESPRIT(MESPRIT) method for harmonic retrieval is presented and analyzed. The estimation of frequencies of sinusoidal signals corrupted by white or colored measurement noise is considered for the MESPRIT method. Monte-carlo simulations are conducted for the comparison of MESPRIT method with TK method in terms of sampled mean, root mean square and relative bias.
