Abstract

This paper aims to overcome the salient deficiency of Orthogonal Frequency Division Multiplexing (OFDM) modulation, namely its high Peak to Average Power Ratio (PAPR). This study is carried out in Digital Video Broadcasting (DVB) context. By first mitigating PAPR with Deep-Clipping solution, the paper dwells on tradeoffs between Modulation Error Rate (MER) and Power Spectral Density (PSD). It is revealed that the proposed technique is very simple and fits DVB standard requirements very well. This solution has been recently successfully implemented in DVB terrestrial and portable modulators.
