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...
One of the main drawbacks of orthogonal frequency division multiplex modulation is its high peak-to-average power ratio (PAPR) which can induce poor power efficiency at high power amplifier. Tone reservation (TR) is the most popular PAPR mitigation technique that uses a set of reserved tones to design peak cancelling signal for PAPR reduction. Finding an effective peak cancelling for PAPR reduction...
In this paper a recently introduced block Decision Feedback Equalizer (DFE) is further studied and developed. Moreover it is shown that the new technique is particularly suitable for channel equalization in applications involving channels with medium up to long impulse response. The new equalizer, which is totally implemented in the frequency domain, offers remarkable savings in computational complexity...
