Smart Antenna

Smart Antenna

Smart antennas (also known as adaptive array antennas, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signature such as the direction of arrival (DOA) of the signal, and use it to calculate beamforming vectors, to track and locate the antenna beam on the mobile/target. The antenna could optionally be any sensor.

Smart antenna techniques are used notably in acoustic signal processing, track and scan RADAR, radio astronomy and radio telescopes, and mostly in cellular systems like W-CDMA and UMTS.

Smart antennas have two main functions: DOA estimation and Beamforming.

Famous quotes containing the word smart:

    Often, we expect too much [from a nanny]. We want someone like ourselves—bright, witty, responsible, loving, imaginative, patient, well-mannered, and cheerful. Also, we want her to be smart, but not so smart that she’s going to get bored in two months and leave us to go to medical school.
    Louise Lague (20th century)
