Dual-Branch CNN for Direction-of-Arrival and Number-of-Sources Estimation

Sensors
Despite numerous conventional direction-of-arrival (DOA) methods, relationships between number of sources (NOS) and DOA are often ignored, which could yield meaningful estimation information.

On Improvements of Cyclic MUSIC

EURASIP Journal on Advances in Signal Processing, 2005
Many man-made signals encountered in communications exhibit cyclostationarity. By exploiting cyclostationarity, cyclic MUSIC has been shown to be able to separate signals with different cycle frequencies, thus, to be able to perform signal selective ...

DOA Estimation for UCAs Based on Virtual Subarray Beamforming Technique

MATEC Web of Conferences, 2018
Direction-of-arrival (DOA) estimation is always a hotspot research in the fields of radar, sonar, communication and so on. And uniform circular arrays (UCAs) are more attractive in the context of DOA estimation since their symmetrical structures have ...

Estimation of Direction of Arrival (DoA) of DVB T signals in mobile receiving configuration

, 2008
To improve the quality of the mobile reception of DVB-T (Digital Video Broadcasting on Terrestrial networks) signal, the knowledge of the propagation channel characteristics is necessary. In this aim, this paper presents sounding methods and results for the estimation of Direction of Arrival (DoA) of DVB T signals in mobile receiving configuration. The

DOA Estimation Based on Logistic Function for CD Sources in Impulsive Noise

IET Signal Processing
To improve direction of arrival (DOA) estimation for coherently distributed sources under impulsive noise environments, a logistic-based adaptive factor is proposed to suppress the impulsive noise contained in the output signals of the array.

Efficient gridless 2D DOA estimation based on generalized matrix‐form atomic norm minimization

Electronics Letters
Two‐dimensional (2D) direction‐of‐arrival (DOA) estimation is crucial in array signal processing. Compressed sensing (CS) provides a superior alternative to spatial spectrum estimation algorithms by enabling 2D DOA estimation of correlated sources from ...
