The method of Spectral Correlation-Signal Subspace Fitting (SC-SSF) fails to separate wideband cyclostationary signals with coherent second-order cyclic statistics (SOCS). Averaged Cyclic MUSIC (ACM) method made up for the drawback to some degree via temporally averaging the cyclic cross-correlation of the array output. This paper interprets ACM from(More)
Radio Specific Emitter Identification (SEI) is the technique which identifies the individual radio emitter based on the received signals' specific properties called signals' Radio Frequency Fingerprint (RFF). SEI is very significant for improving the security of wireless networks. A novel SEI method which treats the emitter as a nonlinear dynamical system(More)
Among the existing sparsity-inducing direction-ofarrival (DOA) estimation methods, the sparse Bayesian learning (SBL) based ones have been demonstrated to achieve enhanced precision. However, the learning process of those methods converges much slowly when the signal-to-noise ratio (SNR) is relatively low. In this paper, we first show that the covariance(More)
