Detailed Documentation

In this article, we explore the MUSIC (Multiple Signal Classification) algorithm in array signal processing and conduct simulations to evaluate its performance under different signal-to-noise ratios (SNR), varying numbers of array elements, and diverse snapshot counts. This original research provides an in-depth analysis of the algorithm's implementation, including key steps such as estimating the sample covariance matrix from received data, performing eigenvalue decomposition to separate signal and noise subspaces, and constructing the MUSIC spatial spectrum using noise eigenvectors. The implementation demonstrates how to identify direction-of-arrival (DOA) estimates through peak detection in the spatial spectrum. The article offers valuable insights into practical considerations for parameter selection and performance optimization in real-world applications.
