Abstract: In this paper, we've an inclination to propose a spanking new theme for data transmission supported orthogonal frequency division multiplexing (OFDM). In OFDM theme we've an inclination to match fast Fourier Transform (FFT) primarily based OFDM with wavelet based technique. In this technique DWT-HAAR (Discrete wavelet Transform) and ADWT-Adaptive lifting theme (Adaptive discrete wavelet Transform) is used for wavelet decomposition, we've an inclination to match ADWTAdaptive lifting theme with ancient DWT-HAAR that reduces procedure complexness and conjointly we've an inclination to prove that ADWT-Adaptive lifting theme wavelet will yield higher performance. we've got a bent to match our wavelet based OFDM with state-of-art criteria like FFT based OFDM, ancient DWT-HAAR based OFDM which we tend to prove that our methodology will yield better results compare to previous methodology supported bit error rate calculation in QPSK, 16-QAM, 64-QAM, 128- QAM, 256-QAM theme.
