Abstract :

In this paper, the performance of Dicrete Wavelet Transform (DWT) based Multi-user MIMO-OFDM is compared with the performance of FFT based MIMO-OFDM system. Wavelet based OFDM has lot of advantages compared to the FFT based OFDM. There is no need for cyclic prefix, flexibility and optimal resolution. Wavelets existed suitably in almost all the arenas of wireless communication schemes with OFDM which is a durable applicant for next peers of wireless scheme, i.e., third generation of partnerships project (3GPP) networks. Simulation created examination will be jumble-sale to simulate the double multicarrier schemes, DWT with Haar constructed multicarrier in addition with the predictable OFDM, less than the consequence of taking multiple antennas scheme, by BPSK and QPSK as dual modulation schemes in an additive white Gaussian noise channel (AWGN). Established on the bit error rate presentation to the transmission ability, the DWT constructed multicarrier scheme was superior to the predictable OFDM scheme.
