An Innovative and Low Complexity PAPR Reduction Technique for Multicarrier Systems

Large peak to average power ratio (PAPR) is a common drawback of multicarrier signals. In wireless communication systems, dealing with high PAPR requires keeping an important margin from the power amplifier compression point. High power amplifier back-off leads to low power efficiency which is not suitable in many embedded systems. In this paper, a new iterative technique to reduce the PAPR of multicarrier signals is presented. The proposed technique called "one-tone one-peak" (OTOP) is based on the tone reservation principles. It has the advantage to be very easy to implement and to give an appreciable PAPR reduction while giving a full control over the reserved tones magnitude
