| 摘 要： | 分析了用光载波抑制耦合基带信号的RoF系统,给出RoF下行链路传输的改进方案:在中心站将基带信号耦合到被抑制掉的频段处传输到基站,并重复利用边带传输上行链路信号.通过仿真得到的系统光谱图、误码率曲线表明:耦合基带信号传输后,下行链路信号的光纤能量损耗降低,基带信号和上行链路信号也具有较好的抗色散能力.

| Abstract: | Analyzing the radio-over-fiber (ROF) system which uses optical carrier suppression coupled with baseband signal to transmit. A scheme which improves the ROF downlink transmission is proposed: use the upper sideband to carry downlink signal, then couple the baseband signal in the frequency where the carrier is suppressed. Finally transmitted to base station over a single mode fiber (SMF), where the low sideband is reused to transmit uplink signal. System spectrum, bit error ratio (BER) curve is generated by ... |
