Frequency Estimation

The book "Frequency Estimation" by Heba Awad Addad Shatnawi addresses the complex challenges of frequency estimation, which are significant in numerous engineering applications. The author presents an improved technique for frequency estimation based on unitary transformation, originally applied in the context of direction of arrival. A central concern of this work is the conversion of a complex-valued autocorrelation matrix into a real data matrix, which facilitates subsequent analysis. This method allows for a more efficient extraction of signal and noise subspaces, as processing real data is generally less cumbersome than that of complex data. Thus, the book provides valuable insights into the mathematical foundations and practical applications of frequency estimation and represents a significant contribution to the literature in this field.
