摘要

在60 GHz毫米波光纤系统中成功演示了正交相移键控(QPSK)、16正交调幅(QAM)和64-QAM数据传输速度为6 MS/s，下行链路记录了良好的误差矢量幅度性能。该系统采用由光相位调制器和DWDM滤波器组成的双波长源，利用光子方法产生60 GHz载波。在128分钟的测量周期内，数据在20公里长的光纤上传输，具有非常好的稳定性。

Multilevel modulated signal transmission for millimeter-wave radio over fiber system

quadrature phase-shift keying (QPSK), 16 quadrature amplitude modulation (QAM), and 64-QAM data transmission at 6 MS/s are successfully demonstrated in a 60 GHz millimeter-wave over fiber system with good error vector magnitude performance recorded for the downlink. The system utilizes a photonic method to produce the 60 GHz carrier by employing a dual wavelength source consisting of an optical phase modulator and DWDM filter. The transmission of the data over a 20 km span of fiber has been performed with very good stability over a measurement period of 128 minutes.
