PAPR comparison of different orthogonal base in multicarrier systems

Abstract

An important discovery about the PAPR in multicarrier modulation (MCM) systems with different orthogonal base is reported at the first time. In this paper PAPR of MCM is gained respectively by employing seven different kinds of orthogonal bases, six of which are wavelet bases and one is the well-known Fourier base. Simulation results show that according to PAPR of Fourier based MCM (OFDM) outperforms those based on wavelet regardless of which wavelet is chosen
