一个新型的毫米波无线信号光纤传输系统及本振信号远程传送结构

摘要提出一个新型的毫米波光纤传输系统及本振信号远程传送的结构.此技术能为将来使用皮蜂窝网络提供宽带无线接入服务给出一个简单的基站接入点解决方案.计算和仿真结果表明,在激光器输出功率为－6.5 dBm,光放大增益为6 dB,激光线宽为1 MHz,75 MHz或150 MHz,误码率不超过10－9的情形下,622 Mbit/s的下行相移键控信号能够在传统单模光纤上传输超过30 km的距离.在具有相对大的激光器线宽150 MHz和光纤距离为30 km时,由激光器相位噪音和光纤色散所引起的（通过远程传送的）毫米波本振信号的额外相位误差的方差仅为1.74°.

A Novel Configuration for Millimeter-Wave Radio-over-Fiber (ROF) Transmission Systems with Remote Local-Oscillator Delivery

A novel configuration for millimeter-wave (mm-wave) radio-over-fiber transmission systems with remote local-oscillator (LO) delivery was proposed. The proposed technique provides a very simple solution to base-station access points for pico-cellular networks in order to distribute the future broadband wireless-access services. Both numerical and simulation results show that,622 Mbit/s binaryphase-shift-keying (BPSK) data in the downlink can be successfully transmitted with a bit error rate ≤10－9 over 30 km of a conventional single-mode fiber,for a laser output power of －6.5 dBm,an optical gain of 6 dB,and laser linewidths (LLw's) of 1 MHz,75 MHz,and 150 MHz,respectively.The variance of an additional phase error of the remotely delivered mm-wave LO due to laser phase noise and fiber dispersion is calculated to be only about 30.4 mrad (1.740°),in the case of the relatively large LLW of 150 MHz and a fiber length of 30 km.
