High Peak to Average Power Ratio (PAPR) is a critical issue in multicarrier communication systems using Orthogonal Frequency\r\nDivision Multiplexing (OFDM), as in the Second Generation Terrestrial Digital Video Broadcasting (DVB-T2) system. This\r\nproblem can result in large performance degradation due to the nonlinearity of the High Power Amplifier (HPA) or in its low\r\npower efficiency. In this paper, we evaluate the performance of different Tone Reservation-based techniques for PAPR reduction in\r\nDVB-T2 context. Also, we propose an iterative TR-based technique called ââ?¬Å?One Kernel One Peakââ?¬Â (OKOP). Simulation results and\r\nperformance comparison of these techniques in terms of gain in PAPR reduction, mean power variation, and complexity will be\r\ngiven. Finally, we describe the implementation of a PAPR reduction algorithm in the DVB-T2 modulator.
