针对FTN（Faster-than-Nyquist）信令中的频域均衡（FDE），提出了一种通过消除块间干扰来有效地添加和去除循环前缀和循环后缀的方法。此外，我们提出了各种传输方案，以整合这样的FTN信令在单载波FDE系统。我们提出了FTN传输方案结合各种FDE技术，如后均衡，预均衡，和平衡均衡的FTN-SC-FDE系统。我们证明了所提出的传输方案产生改进的性能，通过推导的瞬时误码率和错误概率。最后，我们评估各种FTN-SC-FDE方案的性能的分析结果和仿真结果。我们提出的方案可以应用于提高频谱效率的卫星广播系统，如DVB-S2/S2 X以及交互式广播系统的返回信道。
This paper provides a method that appends and removes efficiently the cyclic prefix and the cyclic suffix by means of an inter-block interference elimination for a frequency domain equalization (FDE) in faster-than-Nyquist (FTN) signaling schemes. Furthermore, we propose various transmission schemes to integrate such an FTN signaling in the single-carrier FDE system. We propose FTN transmission schemes combined with various FDE techniques such as a post-equalization, a pre-equalization, and a balanced equalization in the FTN-SC-FDE system. We prove that the proposed transmission schemes yield improved performances by deriving the instantaneous bit error rate and error probability. Finally, we evaluate the analytical results and the simulation results of the performance of various FTN-SC-FDE schemes. Our proposed schemes can be applied to enhance the spectral efficiency of the satellite broadcasting systems like DVB-S2/S2X as well as the return channels of interactive broadcasting systems.
