Wavelet Transform Effect on MIMO-OFDM System Performance

Although latest generations for mobile communications systems have provided flexible expansion in system capacity, they faced great challenge in performance enhancement especially in the presence of bad fading channel conditions. In this paper a modified MIMO OFDM system will be introduced that is capable of mitigating fading channel distortion even in its worst conditions. In most recent researches Wavelet Transform (WT) was applied in stead of OFDM technology but in this paper both WT and OFDM technologies were applied together in order to have more performance enhancement.
