单载波（SC）信号传输具有低峰均功率比（PAPR）的特性，并利用基于最小均方误差（MMSE）准则的频域均衡（FDE）实现频分集增益。本文研究了奈奎斯特滤波宽带SC传输。随着发射滤波器滚降因子的增加，信号带宽增加，PAPR减小。在[15]中提出了基于频谱合并的MMSE-FDE。通过利用发射滤波器引入的多余带宽和使用频谱合并，可以获得额外的频率分集增益。在本文中，我们深入研究了如何影响PAPR、BER性能和吞吐量性能。
Single carrier (SC) signal transmission has a property of low peak-to-average power ratio (PAPR) and achieves the frequency diversity gain by the use of frequency-domain equalization (FDE) based on the minimum mean square error (MMSE) criterion. In this paper, Nyquist filtered broadband SC transmission is considered. As the transmit filter roll-off factor α increases, the signal bandwidth increases and the PAPR reduces. MMSE-FDE using spectrum combining was proposed in [15]. An additional frequency diversity gain can be obtained by making use of the excess bandwidth introduced by the transmit filter and by using spectrum combining. In this paper, we thoroughly investigate how α affects PAPR, BER performance, and throughput performance.
