Multiple Signal Classification

Multiple Signal Classification (MUSIC) is a technique used in signal processing to locate and identify multiple sources of signals, like radio waves or sound sources, from measurements taken by an array of sensors. It analyzes the data's patterns to distinguish the signals' directions, separating them from noise. MUSIC works by mathematically breaking down the data into components associated with the signals and noise, then identifying the angles where signals are strongest. This helps in accurately pinpointing the sources' positions or frequencies, which is useful in applications like radar, sonar, and wireless communications.
