【摘要】 提出一种将重叠频域均衡算法和正交训练序列相结合的方法,以提高偏振复用单载波频域均衡系统的带宽利用率。通过采用重叠频域均衡方法,发送端避免添加循环前缀冗余信息,提高了系统性能。采用正交训练序列,减少序列长度,提高了带宽利用率。仿真研究了224Gb/s PDM-SCFDE的系统性能,并对算法的不同重叠长度和系统性能的关系进行了分析。更多还原

【Abstract】 In the paper, a scheme of joint overlap frequency-domain equalization(OFDE) and orthogonal sequences is proposed to improve bandwidth efficient for PDM-SCFDE system. At the transmitter, cycle prefix(CP) is removed by using OFDE method, thus, it can improve system performance. In addition, training sequences are shorter to improve bandwidth efficient by using orthogonal sequences. Meanwhile, after simulate a 224Gb/s PDM-SCFDE system, the system performance under different overlap length of OFDE is analysis and discussed.更多还原
