The Implementation of MUSIC Algorithm Based on a Multi-DSP Parallel System

Jian Rong-kun

Abstract

MUSIC algorithm is an algorithm in the DOA estimation,it requires intensively real-time estimation,fast calculation and high precision.Computation of the algorithm mainly concentrated on the covariance matrix,matrix eigenvalue decompo-sition and peaks searching.In order to reduce the computational complexity of calculation,a simplified calculation method is proposed.The system is a parallel structure with multi-pieces of TMS320 C6713,and a new method of assigning duties is proosed to enhance the processing speed and acceleration ratio.
