Detailed Documentation

In signal estimation, an indirect approach can be employed to compute the 1.5-dimensional spectrum. The distinctive feature of the 1.5-dimensional spectrum lies in its ability to effectively suppress Gaussian noise while enhancing the representation of low-frequency components. This method can be implemented using higher-order statistical analysis, where key functions like cumulant calculations and Fourier transformations are applied to extract robust spectral features. The algorithm typically involves preprocessing the signal, computing higher-order moments or cumulants, and then applying spectral estimation techniques to derive the 1.5D spectrum. This approach enables more accurate signal estimation and analysis, particularly in noisy environments where traditional spectral methods may underperform.
