Wavelet-OFDM based on the discrete wavelet transform is a multicarrier modulation technique of considerable interest, due to its good performance in several respects such as the peak-to-average power ratio and the interference cancellation, as investigated in the literature. More specifically, the Haar wavelet has been proposed by various researchers as the most attractive wavelet for data transmission. In this paper, we address the power spectral density limitations of Wavelet-OFDM, and we show analytically and experimentally that the bandwidth efficiency of Haar Wavelet-OFDM is significantly poorer than OFDM, having larger main lobe and side lobes compared with OFDM, which reduces the attractiveness of the scheme.
