Design and Implemetation of OFDM System and Reduction of Peak to Average Power Ratio by Hybrid of Hadamard Coding and DAPSK Modulation with Redundant Discrete Wavelet Transform
Jyoti Makkar,  Silki Baghla
This paper design and implement the PAPR reduction technique with an orthogonal frequency division multiplexing (OFDM) system model and provide comparison with the existing system model. Both, of the system model based on hybrid PAPR reduction techniques, but existing model combines Hadamard coding and DAPSK modulation with discrete fourier transform (DFT) and discrete cosine transform (DCT) and the proposed model combines Hadamard coding and DAPSK modulation with the redundant discrete wavelet transform (RDWT) arrangement. All of the above mentioned system considered the AWGN channel. The simulation results prove that the proposed system model is well performed as compared to the conventional system model under Matlab/Simulink.
Keywords- OFDM, FFT, DCT, RDWT, AWGN, DAPSK modulation and PAPR
