Performance Evaluation of Different Adaptive Beamforming techniques for MIMO-OFDM System

In wireless communication, the receiver side BER strongly affected by channels noise, interference, distortion, synchronization error and wireless multipath fading channels, Multiple-input and multiple-output( MIMO) and Orthogonal frequency-division multiplexing (OFDM) system is the use of multiple antennas at both the end in wireless communication to improve BER performance. In this new information high data rate and strong reliability features are becoming the dominant factor for a successful deployment of commercial networks. The specifically, Multiple Input Multiple Output (MIMO) beam-forming is helpful in cancelling such interference since it can spatially suppress some of the multipath. We propose an ICI eliminating beam forming scheme employing a pertone processing approach, an with moderate computational complexity.The results has been shown in the paper for the simulation in various conditions.
