我们总结了实现大容量（>100Gb/s）光纤无线集成系统的几种不同方法，包括光偏振复用（PDM）与多输入多输出（MIMO）接收相结合、高级多级调制、光多载波调制、电多载波调制、天线偏振复用和多频带复用。这些方法可以有效降低信号波特率以及光电设备所需的带宽。我们还研究了大容量光纤无线集成系统中存在的由于无线传输距离不同而导致的无线多径效应等问题。我们证明这些问题可以基于先进的数字信号处理（DSP）算法（包括经典的恒模算法（CMA））得到有效解决。此外，基于这些方法与先进DSP算法的结合，我们成功演示了400G光纤无线集成系统，创造了无线传输容量记录，开创了毫米波频率超高比特率（>400Gb/s）光无线集成通信的新时代。 (c) 2013 年美国光学学会
We summarize several different approaches for the realization of large capacity (>100Gb/s) fiber wireless integration system, including optical polarization-division-multiplexing (PDM) combined with multiple-input multiple-output (MIMO) reception, advanced multi-level modulation, optical multi-carrier modulation, electrical multi-carrier modulation, antenna polarization multiplexing and multi-band multiplexing. These approaches can effectively reduce the signal baud rate as well as the required bandwidth for optical and electrical devices. We also investigate the problems, such as wireless multi-path effect due to different wireless transmission distance, existing in the large capacity fiber wireless integration system. We demonstrate these problems can be effectively solved based on advanced digital-signal-processing (DSP) algorithms including classic constant modulus algorithm (CMA). Moreover, based on the combination of these approaches as well as advanced DSP algorithms, we have successfully demonstrated a 400G fiber wireless integration system, which creates a capacity record of wireless delivery and ushers in a new era of ultra-high bit rate (>400Gb/s) optical wireless integration communications at mm-wave frequencies.
