Transformation of Any Adding Signal Technique in Tone Reservation Technique for PAPR Mitigation Thanks to Frequency Domain Filtering

Free registration required

Executive Summary

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). Thanks to a frequency domain filtering, in this paper, which is an extension of, the authors propose Classical Transformation (CT) and Adaptive Transformation (AT) algorithms to transform Adding Signal techniques (like clipping techniques) to TR techniques in order to benefit of the TR advantages.
