“…The performance evaluation by using pair-wise error probability and linear equalizer for the wireless network has been proposed before. The researcher [9] are considered the diversity technique, but not the IA scheme. So far, there is no literature on performance evaluation of PEP using specific equalization algorithm, IA scheme and diversity order technique (STFBC) in MIMO-OFDMA system, so, this research paper is proposed.…”

Abstract.One of the challenges issue in Orthogonal Frequency Division Multiple Access (OFDMA) is the interference of the system, which is the inter-symbol interference (ISI) and inter-carrier interference (ICI) is being considered. So that, in this paper the interference alignment scheme together with the implementation of the Minimum Mean Square Error (MMSE) equalizer is proposed to be adopted in wireless network, OFDMA system. The objective of this study is to evaluate the Pairwise Error Probability (PEP) performance of the presented study and the simulation results show that the PEP performance is improved when implementing the interference alignment, and further improved when implementing the scheme with the MMSE equalizer. The effect of ICI and ISI can be reduced and the maximum diversity of the system is achieved by using the proposed Interference Alignment scheme, and implementation of equalizer.

This review paper is about the schemes of removing the inter carrier interference in the multiple input multiple output-orthogonal frequency division multiplexing system. The inter carrier interference occurs by the frequency offsets. In the cellular communication system the inter carrier interference arises due to the fully loaded traffic conditions at the cell edge .which is removed by the combining the multiple cell coordinated or frequency reuse .The inter carrier interference occurs when the cyclic prefix length lesser than the channel impulse response .To mitigate this interference use the spatial diversity techniques are used. In this method by using the spatial techniques the length of the cyclic prefix becomes more than the channel impulse response. The inter carrier interference can also be removed by the single input multiple output but this is not the better method to remove the inter carrier interference as it does not remove the inter carrier interference properly. Inter carrier interference arises when the wireless channel estimation is done with the help of Doppler spread information and the data symbols detector. In the wireless channel estimation the inter carrier interference is removed by the parallel interference cancellation and the decision statistically combining method .The parallel interference cancellation and decision statistically combining methods are used at the receiver end.
