| Abstract | ||||
| Pisarenko method is an important technique to estimate the sinusoidal signal frequencies in white noise. In this paper, we show that the assumption of fair white noise and its corresponding equal values diagonal covariance matrix can be perturbed in some noise environments. Therefore, the simple criterion form of Pisarenko is not suitable and other modified algorithms are to be proposed to alleviate this problem. These algorithms and their results are shown. | ||||
