摘要

由于无线系统对高数据速率和高容量的要求越来越高，基于小波变换的OFDM (W-OFDM)技术成为一种关键的解决方案。W-OFDM采用正交小波，看到正交小波包含了由于多径衰落环境而减少ISI和ICI影响的额外潜力，并且与传统OFDM (C-OFDM)[1]相比，提供了额外的带宽效率。此外，为了增加容量范围，同时具有突出的数据速率和可靠的性能，MIMO方法被认为是使用多天线的一种战斗技术。本文给出了MIMO-W-OFDM在不同调制方式下提高带宽效率的误码率评价。此外，与传统的MIMO-OFDM结合无线系统的性能比较表明，MIMO-WOFDM提高了误码率。

BER Assessment of MIMO Incorporated W-OFDM Wireless Communication System

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.
