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 new type of millimeter-wave optical fiber transmission system and the structure of long-distance transmission of local oscillator signal are proposed, which can provide a simple base station access point solution for providing broadband wireless access service in the future by using a picocellular network. The calculation and simulation results show that , A phase shift of 622 Mbit / s at a laser output of -6.5 dBm, an optical gain of 6 dB, a laser linewidth of 1 MHz, 75 MHz or 150 MHz and a bit error rate of no more than 10-9 The key signal transmits over 30 km over conventional single-mode optical fiber, which is caused by laser phase noise and fiber dispersion at a relatively large laser linewidth of 150 MHz and a fiber distance of 30 km ) The variance of the extra phase error of the millimeter wave local oscillator signal is only 1.74 °.
