- W2364253268 abstract "This paper make a research on the relationship between DOA estimation and constant modulus property and propose a simple direction estimation algorithm based on LS-CMA blind beamforming for multiple sources and polynomial extraction. Purpose to analyzes the estimation performance of the algorithm, this paper also derives the Cramer-Rao bounds (CRB) of CM signals for arbitrary array configurations and specialize to uniform linear arrays. It has been demonstrated that this algorithm almost achieve the CRB and has perfect performance contrast to MUSIC,ESPRIT which that without concerning for the property of CM, especially under the environment of few samples and low SNR. In addition , it can estimate the weak sources when the stronger sources are not removed, as well as the computational complexity will not increase for without using spectra search. Computer simulations proves correctness and effectiveness of this new algorithm." @default.
