BER Assessment of MIMO Incorporated W-OFDM Wireless Communication System

Abstract

Due to elevated demands of high data rates and capacity for wireless systems, Wavelet based OFDM (W-OFDM) comes out as a key solution. W-OFDM is employed using orthogonal wavelets, seeing that orthogonal wavelets enfold additional potential of reducing ISI and ICI effects due to multipath fading environment and offers additional bandwidth efficiency as compare to conventional OFDM (C-OFDM) [1]. Furthermore, to increase capacity range in conjunction with prominent data rate and reliable performance, an approach of MIMO has been acclaimed as a combative technique with the use of multiple antennas. In this paper, BER evaluation of MIMO-W-OFDM for improving bandwidth efficiency by means of various modulation schemes is exhibited. Furthermore, a performance comparison with the conventional MIMO-OFDM incorporated wireless system is demonstrated which reports an improved BER with MIMO-WOFDM.
