In recent years, high-speed wireless communication is in vogue. In wireless communication systems, multipath fading, delay and interference occurred by reflection or diffraction. In a high-speed wireless communication, it becomes a necessity to separate desired signal from delay or interference signal. Thus to overcome these problems Smart antenna systems have been developed. Smart antennas employ a set of the radiating elements that are combined to form a movable or switchable beam pattern that follows the desired user. The arrays by themselves are not smart, it is the digital signal...
