摘要

我们比较了在毫米波频段工作的无线部分通过光纤无线架构的第五代前传通信网络分配信号的三种选择:基带、中频带和射频带。结果表明，该方法有效应用于中频传输的优势，并通过仿真加以验证。研究表明，即使在毫米波频段较低的部分，当光纤链路的最大长度比中频波段的传输短3倍时，即使使用最有前途的光调制器，也能达到64-QAM EVM限制的标准。

Studying an Optimal Approach to Distribute Signals through Fiber-Wireless Fronthaul Network

We compare the three options of distributing signals through fifth-generation fronthaul communication network of fiber-wireless architecture with a wireless section operating in MMW-band: in baseband, in intermediatefrequency band, and in radio-frequency band. In the result, the advantage of effective application for intermediatefrequency band transmission are defined and confirmed by a simulation. The study showed that even in the lower part of the MMW-band, the standard for 64-QAM EVM limit was achieved when the maximum length of the fiber-optics link was 3 times shorter compared to transmission at IF-band even when using the most promising type of optical modulator.
