A novel approach that does not require the number of sources as a priori is proposed to
estimate the direction of arrival (DOA) based on a sparse non-uniform linear antenna array …

Source enumeration is an important procedure for radio direction-of-arrival finding in the
multiple signal classification (MUSIC) algorithm. The most widely used source enumeration …

A novel direction of arrival (DOA) estimating method is proposed based on the coprime
array, which can work without a priori information of the source number. The fourth-order …

Physical layer security (PLS) provides an additional protection layer to the conventional
encryption in the presence of an active eavesdropper (Eve). The detection of pilot …

Accurate and efficient estimation of the boundary between the signal and the noise
subspace is a critical task in the estimation of high-resolution range-Doppler (RD-HR) maps …

Source number estimation is one of the key problems in blind signal separation. In order to
solve the problem of weak anti-noise ability of the current method, this paper improves the …

This paper describes how a priori information about the signal parameters can influence the
accuracy of estimating the number of these signals. This study considers sinusoidal signals …
