MUSIC algorithm

The MUSIC (Multiple Signal Classification) algorithm is a method used in signal processing to identify the directions or sources of multiple signals received by an array of sensors, like antennas or microphones. It works by analyzing the combined signals to distinguish the true signal directions from noise, effectively separating overlapping signals. MUSIC constructs a mathematical spectrum that highlights potential source angles, allowing precise estimation even in complex scenarios. This technique is widely used in applications such as radar, wireless communications, and audio source localization for accurate and efficient direction finding.
