Abstract
An alternative to the conventional orthogonal frequency division multiplexing (OFDM) scheme is to exploit the self and mutual orthogonality properties of wavelet packet basis function for multiplexing purposes. These systems are known as discrete wavelet transform based OFDM (DWT-OFDM) systems. In this paper a DWT-OFDM transceiver is implemented and the peak to average power ratio (PAPR) in DWT-OFDM signal is analysed. Simulations are carried out to select the best wavelet packet basis function to decrease the PAPR
