PAPR characteristics in spectrum suppressed transmission and transmission quality improvement by equalization

Abstract

In single carrier transmission, spectrum suppressed transmission that increase frequency utilization efficiency by suppressing required bandwidth of a 3dB bandwidth while maintaining throughput by FEC (forward error correction) has been proposed. However, spectrum suppressed transmission has been evaluated only between suppression ratio and frequency utilization efficiency, PAPR which have an impact on transmitter hardware size not considered. Therefore, in this paper, we have evaluated relationship between suppression ratio and PAPR when suppressed modulating spectrum by using low pass, high pass, and band pass filters. Moreover, in the smallest PAPR, we revealed that transmission quality increase further by applying FEC with equalizer to receiver.
