Adaptive Clipping for a Deterministic Peak-To-Average Power Ratio

Diallo Mamadou Lamarana, Jacques Palicot

Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is the most commonly used multicarriers modulation in telecommunication systems due to the efficient use of frequency resources and its robustness to multipath fading channel. However, as multicarriers modulation in general, OFDM suffers from high Peak-to-Average Power Ratio (PAPR). Many works exist in literature for PAPR mitigation among which Clipping is one of the most efficient adding signal techniques in terms of numerical complexity. However, clipping techniques is a probabilistic technique for PAPR mitigation. In other words, the instantaneous PAPR of each clipped OFDM symbol depends on its content and then the PAPR at any value of the Complementary Cumulative Distribution Function (CCDF) increases when its corresponding CCDF values decreases. In this paper, we propose an adaptive clipping which offers a constant PAPR, so deterministic, at any value of the CCDF and so this approach outperforms the classical clipping in terms of signal degradation with the same performance in terms of PAPR reduction. Simulation results validate the interest of this approach.
