为了提高无线通信的可靠性,针对传统无线网络的缺陷,提出一种相位调制器的全双工光纤无线通信系统。首先对当前无线通信系统的研究现状进行了分析,然后采用相位调制器产生毫米波信号,采用交叉复用器对毫米波信号进行处理,产生下行基带信号和上行传输的基带数据,最后实现了全双工光纤无线通信系统,并对其性能进行模拟测试。结果表明,全双工光纤无线通信系统降低了通信成本和数据传输的误码率,提高了信号的传输距离。
In order to improve the reliability of wireless communication, aiming at the defects of traditional wireless networks, a phase modulator full duplex optical fiber wireless communication system is proposed. First of all, the current research status of wireless communication system is analyzed. Then the phase modulator is used to generate the millimeter-wave signal, and the cross-multiplexer is used to process the millimeter-wave signal to generate the downlink baseband signal and the uplink transmission baseband data. Finally, Duplex optical fiber wireless communication system, and its performance simulation test. The results show that the full-duplex optical fiber wireless communication system reduces the communication costs and the bit error rate of data transmission, and improves the signal transmission distance.
