This paper discusses a simple method of Peak to Average Power Ratio (PAR) reduction developed for system with WFMT modulation. The novel Wavelet based Filtered Multi-Tone (WFMT) modulation was proposed as an alternative of the Discrete Multi-tone line code for xDSL system and represents future extending of OFDM/ DMT technologies. Because of multicarrier nature of WFMT modulation, it is well suited to carry high-speed data over a wide frequency band. As it is well known, the major drawback of the multicarrier system is the large PAR of the transmit signal, which renders a straightforward implementation costly and inefficient. In this paper, we describe a new PAR reduction technique based on an overlapping structure of a WFMT signal. We examine the WFMT PAR characteristics by SIMULINK Model of a Cable TV Broadcast System, described in [1]. The results illustrate a significant PAR reduction of the WFMT transmit signal when the proposed method is used.
