DOA Estimation of GNSS Signals Based on Deconvolved Conventional Beamforming

Remote Sensing
The Direction of Arrival (DOA) parameter is a key parameter in directional channel modeling for GNSS systems and multipath suppression. However, achieving high-precision, low-complexity DOA estimation of multiple signal sources without requiring a known ...

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

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

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.
