JIN Liang; YIN Qin-ye; WANG Yi-lin; (1. University of Information Engineering ,Zhengzhou 450003 China 2. Information Engineering Institute,Xi'an Jiaotong University ,Xi'an 710049, China)  
In this paper we propose a method called Generalized Spectral Correlation Signal Subspace Fining (GSC-SSF) for DOA estimation, which is applicable in both wide and narrow band scenarios. Especially, in narrow band cases, the method is capable of enlarging the effective aperture of sensor array considerably. It is proven herein that Several present DOA estimation method based on cyclostationarity including SC-SSF, Cyclic MUSIC and Cyclic ESPRIT are just the special cases or approximation of this method Its effectiveness and generality are illustrated by the simulation results.
