| Abstract(in English) | We have studied OFDM/FM (Orthogonal Frequency Division Multiplexing over Frequency Modulation) scheme for high-speed satellite communication systems. In this study, we apply several companding methods to OFDM signals to decrease the dynamic range and to increase the efficiency of OFDM/FM signal in the frequency region. As companding methods, we consider μ-law, A-law, and non-linear companding methods. Besides, we also consider emphasis and de-emphasis methods to avoid low SNR (Signal-to-Noise Ratio) in higher frequency region due to FM. We perform computer simulation of OFDM/FM scheme with companding and emphasis to evaluate BER (Bit Error Rate) performances and the 99 percent bandwidth. |
