中文摘要	In the case of uniform linear array (ULA) system, it is found that the interference eigenvalue asymptotes to the periodically extended version of the interference spatial spectrum. This fact was then employed in estimation on the number of interference degrees of freedom (DoF) ,i.e. ,the number of significant interference eigenvalues, in the presence of various non-ideal effects . The proposed method first employs covariance matrix tapers to obtain the interference covariance function and its corresponding spatial spectrum in non-ideal scenarios. Then the number of interference DoF is estimated according to the periodically extended spectrum.The simulations agree with the estimation results.
