Orthogonal Frequency Division Multiplexing (OFDM) suffers from a high Peak-to-Average Power Ratio (PAPR). Tone Reservation (TR) is a popular PAPR reduction technique that uses a set of reserved subcarriers to carry the peak reducing signal. The major advantages of TR technique include no transmission performance degradation, no transmission of Side Information (SI) and downward compatibility. Because of all these benefits, TR seems to be promising for use in commercial standards such as Digital Video Broadcasting - Terrestrial (DVB-T2). In this paper, due to a filtering based on FTT/IFFT pair, we propose to transform many adding signal techniques (like clipping techniques) to TR techniques in order to benefit of the TR advantages. As the transformation is a low-complexity process (about the FTT/IFFT complexity), the obtained technique results in a low-complexity TR technique. However, the transformation generates a loss of performance in PAPR reduction which can be improved by iterating the process of transformation. Later in the paper, the classical clipping technique is transformed to a TR technique called ``clipping-based TR'' technique and simulations results show that, for the same value of clipping level, clipping technique is better than ``clipping-based TR'' in terms of PAPR reduction, but ``clipping-based TR'' does not degraded the BER of the system unlike the clipping technique
