Review ofFuzzy Logic based Adaptive Antenna Array system

Abstract

This paper deals with a scheme to realize a smart and adaptive antenna for the Mobile
base-station using Fuzzy Logic Control. This "Fuzzy Logic based Adaptive Antenna Array system"
determines the required deviation of angle (DOA) to be brought in for controlling the orie ntation of
the base station antenna beam towards the mobile unit. It can also take care of the varying and
uncertain feature inherent to the mobile unit tracking' process besides incorporating the effect of the
random weight fluctuation.Adaptive array antenna technology represents the most advanced smart
antenna approach. Using a variety of new signal-processing algorithms, the adaptive system takes
advantage of its ability to effectively locate and track various types of signals to dynamically
minimize interference and maximize intended signal reception.
