Abstract

This paper is concerned with how to implement the MUSIC algorithm in a high-speed way. The key point in transplanting an algorithm into a practical application is to find a way to simplify the algorithm´s computational complexity so that it can be implemented by the system hardware. A design is proposed in this paper, which shows that the MUSIC algorithm can be simplified effectively by using a preprocessing method or other methods, and that a parallel processing approach can greatly improve processing speed.
