摘　　要：采用相移键控(PSK)调制技术设计了副载波复用-光载无线通信(SCM-RoF)系统,分析了SCM-RoF信号的时域和频域特性,研究了不同用户的传输性能及发射端和接收端带通滤波器(BPF)、用户传输速率对SCM-ROF系统的影响.结果表明:不同用户间传输效果略有差异,而发射端和接收端的BPF也会对系统产生影响,当用户传输速率在2 Gbit/s左右时,系统传输性能与系统利用率达到最佳平衡,误码率(BER)在10^(-10)数量级.Subcarrier multiplexing-radio over fiber(SCM-RoF)system based on phase shift keying(PSK)isdesigned.The time and frequency domain characteristics of SCM-RoF signal are analyzed,and the influence ofbandpass filter(BPF)at transmitter end and receiver end and the transmission rate on the SCM-ROF system and thetransmission characteristics of different users are studied.The results show that the transmission performance amongdifferent users is slightly different,and BPF at transmitter end and receiver end can also affect the system transmission performance.When the user transmission rate is at about2Gbit/s,the system performance and transmission efficiency can achieve the best balance,and the bit error rate(BER)is about10-10.
