DOA Estimation Based on Real-Valued Cross Correlation Matrix of Coprime Arrays
Sensors, 2017 A fast direction of arrival (DOA) estimation method using a real-valued cross-correlation matrix (CCM) of coprime subarrays is proposed. Firstly, real-valued CCM with extended aperture is constructed to obtain the signal subspaces corresponding to the ...

Selective Range Iterative Adaptive Approach for High-Resolution DOA Estimation
IEEE Access, 2019 In this paper, the problem of direction-of-arrival (DOA) estimation for a uniform linear array with single-snapshot observations is addressed. Two non-parametric DOA estimators are developed, which can be applied in any azimuth range with one snapshot ...

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 ...

Joint DOA and TOA estimation method based on Pareto multi-task learning
上海师范大学学报. 自然科学版A joint estimation method for direction of arrival （DOA） and time of arrival （TOA） was proposed based on Pareto multi-task learning， which transformed the traditional multi-task learning problem into a multi-objective optimization problem for solution. A
