摘要

实验分析了导频音数对光纤到户(FTTH)网络中正交频分复用(OFDM)超宽带信号传输的影响。本文分析了在适当的FTTH距离下，多通道OFDM-UWB传输的预期到达范围和性能。考虑了放大截面和标准单模光纤。实验结果表明，FTTH到达/性能与用于估计均衡器传递函数的导频音的数量有很强的依赖性。研究结果表明，导频信号的数量是在光学系统上传输超宽带无线电信号时需要考虑的一个重要参数。

Impact of pilot tone-assisted equalization in Wimedia-defined OFDM-UWB signals transmission in FTTH networks

The impact of the number of pilot tones in Wimedia-defined orthogonal frequency-division multiplexed (OFDM) ultra wideband signal (UWB) transmission over fiber-to-home (FTTH) networks is experimentally analyzed. This paper analyses the expected reach and performance of multichannel OFDM-UWB transmission in adequate FTTH distances. Amplified section and standard single-mode fiber are considered. The experimental results indicate a strong dependence of the FTTH reach/performance on the number of pilot tones used to estimate the equalizer transfer function. The results reveal the number of pilot tones as an important parameter to be considered in UWB radio signals transmission over optical systems.
