Adaptive Beam Forming of MIMO System using Low Complex Selection of Steering Vector

Abstract

With the superior growth of digital communication the need for high-speed data transmission has increased. In that, Orthogonal Frequency Division Multiplexing (OFDM) is multi-carrier modulation techniques, which partition the single spectrum into numerous sub-carriers. The major benefit of OFDM is their significance towards channel fading in wireless environment. In wide range data transmission, the OFDM is heavily affected by the Inter Symbol Interface (ISI). To diminish ISI, an Adaptive Analog Beam Forming (AABF) based Phased Array Antenna (PAA) is introduced. PAA achieves the reduction of noise significantly and also shows improvement in the effectiveness of reducing the side lobe ranges with narrow beam width. The experimental outcome proves that the proposed system performs effectively than the other existing systems.
