Sensor Placement to Improve the Positioning Performance Based on Angle of Arrival (AOA)
Wireless Engineering and Technology, 2010 In this paper, a method for sensor placement to improve the placement quality based on angle of arrival of signal in a specific area is proposed. The installation place of sensors may be constrained with specified boundaries. In this me-thod, the criterion of maximum quality of placement is the Cramer-Rao bound.
