在这封信中，我们提出了一个可扩展的高速W波段（75-110-GHz）光纤无线通信系统。通过使用光频率梳发生器，三通道8.3-Gb/s/ch光正交频分复用（OOFDM）基带信号在15 GHz带宽从光到无线域无缝转换。利用自激激光器对OOFDM基带信号进行外差混频，产生W波段无线载波。采用W波段电子下变频器和基于数字信号处理的接收机。三通道QPSK-OFDM W波段无线信号分别在使用和不使用22.8公里单模光纤的情况下在0.5米和2米的空中距离上传输，所实现的性能低于前向纠错限制。
In this letter, we present a scalable high-speed W-band (75-110-GHz) fiber wireless communication system. By using an optical frequency comb generator, three-channel 8.3-Gb/s/ch optical orthogonal frequency-division-multiplexing (OOFDM) baseband signals in a 15-GHz bandwidth are seamlessly translated from the optical to the wireless domain. The W-band wireless carrier is generated from heterodyne mixing the OOFDM baseband signal with a free-running laser. A W-band electronic down-converter and a digital signal processing-based receiver are used. Three-channel QPSK-OFDM W-band wireless signals are transmitted over 0.5- and 2-m air distance with and without 22.8-km single-mode fiber, respectively, with achieved performance below the forward error correction limit.
