Performance Comparison of FFT & Dwt Based OFDM with Alamouti Encoding Over Reyleigh Fading Channel

J. Sudha Rani, K. J. Arvind Chary

This examines the enactment of wavelet based on MIMO OFDM systems and also compare with the performance of FFT based MIMO OFDM. Wavelet based OFDM has more advantages compare to the FFT based OFDM. There is no necessity for cyclic prefix, more flexibility and optimal resolution. Wavelets want existed suitably in almost absolutely the arenas of wireless communication schemes with OFDM which is a durable applicant for next peers of wireless scheme. Simulation created examination will be jumble-sale to simulate the double multicarrier schemes, DWT with Haar mother construction multicarrier in addition the predictable OFDM, less than the consequence of taking multiple antennas scheme, by BPSK modulation schemes in Rayleigh fading channel. Established on the bit error rate presentation to the transmission ability by using Alamoutis algorithm, the DWT constructed multicarrier scheme was establish to be higher to the predictable OFDM scheme.
