Zusammenfassung
High Peak to Average Power Ratio PAPR is the major drawback of Orthogonal Frequency Division Multiplexing OFDM system. In this paper, we propose Zadoff-Chu matrix Transform ZCT precoding Selected Mapping SLM based OFDM SLM-OFDM system for PAPR reduction. This technique is based on precoding the constellation symbols with ZCT precoder matrix row-wise after the multiplication of phase rotation factor and before the Inverse Fast Fourier Transform IFFT in the SLM based OFDM SLM-OFDM Systems. At the clipping rate of 10-3, simulation results show that our proposed system can reduce the PAPR up to 6.8 dB with N=64 or 256 System subcarriers and V=16 Dissimilar phase sequences for 4QAM modulation. ZCT based SLM-OFDM system can avoid signal degradation in performance when passes through a nonlinear High-Power-Amplifier HPA . A. A. A. Wahab | L. T. Zhan | H. Husin | W. A. F. W.
