This paper describes the mathematic model of TLS-ESPRIT algorithm and the definition and properties of fourth order cumulant,and a novel TLS-ESPRIT algorithm based on cyclic fourth order cumulant is proposed. The performance figures of the novel TLS-ESPRIT algorithm and common TLS-ESPRIT are obtained by computer simulation,and the simulation results show that this new algorithm can get rid of not only Gaussian color noise but also the interference in different cyclic frequency. The operation time for the same operation by using different DOA algorithms is simulated, and the simulation results show that this algorithm has lower computational complexity.
