| 摘 要： | 为了进一步提高单载波(SC)系统的频谱利用率,提出了一种新的时域重叠单载波传输方案-OVSC。研究了该系统的频谱利用率、性能及峰均比。为了降低OVSC检测的复杂度,提出了基于频率域均衡(FDE)的次优算法-J-FDE,进一步研究了软输出迭代频率域均衡算法-JI-FDE。最后讨论了基于FDE的OVSC传输方案(OVSC-FDE)的帧结构和导频设计。计算机仿真表明,OVSC-FDE传输方案的性能优于相同频谱利用率下使用多电平调制的OFDM和SC-FDE系统。

| Abstract: | A novel time-domain overlapped single-carrier(SC) broadband scheme OVSC was proposed to improve the spectrum efficiency of the SC transmission system. The spectrum efficiency,the performance,and the peak-to-average power ratio of the scheme were studied. A suboptimum detection algorithm(J-FDE) based on the frequency domain equalization(FDE) was developed and the soft output iterative FDE algorithm JI-FDE was studied. The pilot design and the frame structure were investigated for the proposed OVSC-FDE scheme... |
