摘要：Now a day’s OFDM is widely used in various application mainly in wireless communication. It suffers from Inter symbol Interference (ISI). To mitigate the effect of ISI the cyclic prefix (CP) is used resulting loss in bandwidth. So DWT and WPT are used in place of FFT. By these transform the spectral containment of the channel is better since they are not using CP. In this paper we have compared the FFT based OFDM with DWT, WPT and IWPT-OFDM. IWPT-OFDM has been suggested to improve BER – performance.
