Abstract

The current and future wire line and wireless communications systems use the Orthogonal Frequency Division Multiplexing (OFDM) modulation technique since it has many advantages over the single carrier modulation methods. However, it has a main drawback represented by the high peak to average power ratio (PAPR). To overcome this problem, many techniques have been proposed such as the Selected Mapping (SLM). In this paper, an additive scale factor of zero resultant in the complex plane preceded by the Discrete Fourier Transform (DFT) matrix as a channel coding technique. The PAPR has been reduced significantly (by 3dB) with high reduction in the computational complexity. This is seen in the simulation results where the Bit Error Rate (BER) did not have any effects.
