摘要

在单载波传输中，频谱抑制传输通过抑制3dB带宽的带宽来提高频率利用效率，同时通过前向纠错(FEC)保持吞吐量。然而，频谱抑制传输的评价只考虑了抑制比和频率利用效率，而没有考虑PAPR对发射机硬件尺寸的影响。因此，在本文中，我们评估了使用低通、高通和带通滤波器抑制调制频谱时抑制比和PAPR之间的关系。此外，在最小的PAPR下，我们发现通过对接收机施加均衡器FEC可以进一步提高传输质量。

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

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.
