Utilization of Multiple Antennas for Positioning

Radio-based positioning performance is affected by a range of factors such as radio propagation conditions, node configurations, location determination algorithms, signal design, and signal parameter estimation. To improve positioning accuracy various algorithms and techniques have been developed, among which is the utilization of multiple antennas. If transmitter nodes, receiver nodes (or both) are equipped with multiple antennas, appropriate signal processing algorithms can be exploited to determine the location of a mobile node. This chapter provides a comprehensive coverage on the utilization of multiple antennas for positioning.
