WebTherefore, appropriately combining covariance- and cumulant-based techniques into one scheme, it is possible to obtain an algorithm with an improved robustness. In this paper, … WebAbstract The algorithms developed in this paper rely on cumulants, or higher-order statistics, to eliminate Gaussian noise. A simple relation between the signal model parameters and the cumulant matrices computed from the received signals forms the basis for the development of these algorithms.
WebFeb 4, 2012 · Cumulant-based approximations are implicitly based on polynomial functions, which usually grow fast with the signal amplitude. As a result, higher-order cumulants, including kurtosis, are rather sensitive to outliers, so that only a few possibly erroneous observations can have a drastic effect on the estimation quality. WebJan 20, 2024 · In this paper, a high-order cumulant MUSIC-like method is proposed for mixed-field source localization. This method is based on a non-Hermitian matrix et estimates the DOA and range in a decoupled way. The mathematical development is straightforward, there are some small novelties in the paper. However, there are many …
