Direction of arrival (DOA) parameter estimation with the SAGE algorithm

Signal Processing, 2004
In this study, we investigate the estimation of the relative delay, the azimuth and elevation angle and the complex amplitude of a known received signal with the space alternating generalised expectation (SAGE) maximisation algorithm. This optimisation algorithm is used to replace the high-dimensional optimisation procedure, necessary to compute the ...

Improved maximum likelihood spectrum for direction of arrival (DOA) estimation

ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003
A variation of J. Capon's (1969) maximum-likelihood (ML) spectral estimation algorithm is described for calculating direction of arrival using a short linear array. The proposed modification involves altering the computed covariance spectral matrix by setting its lowest eigen value to a small, positive constant lambda '(min).

A SYSTOLIC ARCHITECTURE FOR CAPON'S DIRECTIONS-OF-ARRIVAL (DOA) ESTIMATION METHOD

Parallel Algorithms and Applications, 1993
In this paper, a systolic array architecture is designed for the parallel implementation of Capon's direction-of-arrival estimation method in array signal processing. The architecture uses the QR decomposition on the data matrix to compute Capon's angular spectrum. The systolic array employs N(N + l)/2 + N processing elements (PEs).

DOA(Direction of Arrival) with array antennas based on MOM

2010 IEEE Antennas and Propagation Society International Symposium, 2010
It's an important issue that estimation of signal direction for radar or communication system. And it was researched for military and commercial. Generally, it's a method that estimate to direction of signal by use each signal of array sensors. It called to DOA(Direction Of Arrival). For basically, there are Beamforming, Capon, Linear-prediction method.

Direction of arrival (DOA) determination based on monopulse concepts

2000 Asia-Pacific Microwave Conference. Proceedings (Cat. No.00TH8522), 2002
Monopulse is a classical radar technique of precise finding of a source or target. The concept can be used both in radar applications as well as in modern communication techniques. The information contained in antenna sidelobes normally disturbs the determination of DOA in the case of a classical monopulse system. The suitable combination of amplitude-

On direction-of-arrival (DoA) feedback and precoding for D2D assisted massive MIMO

2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018
Effective channel state information (CSI) feedback design is difficult for massive multiple-input multiple-output (MIMO) downlink transmissions in 5G frequency division duplexing (FDD) bands, where partial CSI could be directly exchanged between users through device-to-device (D2D) communications.

Direction-of-arrival methods (DOA) and time difference of arrival (TDOA) position location technique

Proceedings of the Twenty-Second National Radio Science Conference, 2005. NRSC 2005., 2005
This paper provides a detailed overview of the various methods for estimation of direction-of-arrival (also called angle-of-arrival) of a radio signal using an antenna array. The array-based directional-of-arrival (DOA) estimation techniques considered here are broadly divided into two different types: conventional techniques, and subspace based ...
