A blind intrapulse modulation recognition based on energy focusing efficiency test was proposed, which can be used to estimate the modulation type under low signal to noise ratio (SNR) conditions. The observed signals were pre-processed by short time

For tacking and localizing sources in the mobile wireless sensor network, underdetermined direction of arrival (DOA) estimation with high-accuracy is a crucial issue. In this paper, a novel sparse array configuration is developed for accurate DOA est

A credibility test method based on approximate entropy (ApEn) is proposed to evaluate the blind processing results of BPSK signals in Cognitive Radio (CR). In the absence of a priori knowledge for the signals, the reference signals were constructed d
