Direction-of-Arrival (DOA) Estimation Based on Real Field Measurements and Modified Linear Regression

This study applied modified linear regression in machine learning (ML) to predict the direction of arrival (DoA) in cellular networks using field measurements and radiofrequency parameters. Models were developed from base station data, with preprocessing

An Efficient Sparse Representation Algorithm for Direction-of-Arrival Estimation

, 2013
This paper presents an efficient sparse representation approach to direction-of-arrival (DOA) estimation using uniform linear arrays. The proposed approach constructs the jointly sparse model in real domain by exploiting the properties of centro ...
