This paper examines the performance of Wavelet based Multi-User MIMO OFDM (MU- MIMO WOFDM) systems and a comparison is made with classical FFT based multiuser MIMO OFDM system. Wavelet analysis has some strong advantages over fourier analysis, as it allows a time-frequency domain operation, allowing optimal resolution and flexibility. Wavelets have been satisfactorily applied in almost all the fields of wireless communication systems including OFDM which is a strong candidate for next generation of wireless system.
