Title

PAPR Reduction in OFDM System using M2M DWT Scheme

Abstract

In this work OFDM system has been implemented with the distinguish wavelets with MSK modulation scheme, & named as M2M- DWT OFDM. Using the MSK modulation reduction in the implementation complexity is achieved, & also no need of channel estimation or equalization. Also, MSK is a minimum variation modulation and demodulation technique that compensates the channel effect on the signal without the need of any previous knowledge of the channel. AWGN channel model has been considered, since AWGN is a result of several independent noise sources which can be possibly added to the signal. Different wavelets sets have been taken & for them BER & PAPR analysis has been simulated. Simulation results shows that PAPR is reduced, with the use of DWT, instead of conventional DFT or FFT. Also, due to the inherit added advantage of wavelet based system, this system does require use of cyclic prefix, hence overall bandwidth efficiency is also more, as compared to the conventional FFT based OFDM.

Key Words
