Direction of Arrival (DOA) Estimation
The smart antenna system estimates the direction of arrival of the signal, using techniques such as MUSIC (Multiple Signal Classification), estimation of signal parameters via rotational invariance techniques (ESPRIT) algorithms, Matrix Pencil method or one of their derivatives. They involve finding a spatial spectrum of the antenna/sensor array, and calculating the DOA from the peaks of this spectrum. These calculations are computationally intensive.
Matrix Pencil is very efficient in case of real time systems, and under the correlated sources.

Famous quotes containing the words direction, arrival and/or estimation:
“Dressed to die, the sensual strut begun,
With my red veins full of money,
In the final direction of the elementary town
I advance for as long as forever is.”
—Dylan Thomas (1914–1953)
“National literature does not mean much these days; now is the age of world literature, and every one must contribute to hasten the arrival of that age.”
—Johann Wolfgang Von Goethe (1749–1832)
“No man ever stood lower in my estimation for having a patch in his clothes; yet I am sure that there is greater anxiety, commonly, to have fashionable, or at least clean and unpatched clothes, than to have a sound conscience.”
