Spectral estimation is a crucial aspect of signal processing, as it allows us to analyze and understand the frequency content of a signal. The goal of spectral estimation is to estimate the power spectral density (PSD) of a signal, which describes how the power of the signal is distributed across different frequencies. Traditional methods of spectral estimation, such as the periodogram and Welch’s method, have been widely used for decades. However, these methods have limitations, such as low resolution and high variance, which can lead to inaccurate estimates. Spectral estimation is a fundamental concept in signal
