摘要

本文描述了光纤无线电系统方案，该系统的无线电域在75-110 GHz (w波段)范围内进行。提出了在RoF光纤领域中给定轨道角动量光信号(OAM信号)的生成方法。该方法是基于应用两个独立的激光器，在近波长工作和空间相位调制装置。为了进行仿真和系统参数计算，提出了基于简化波动方程系统的OAM信号包络数学模型。对这些信号在传输过程中的包络进行了计算机模拟。结果表明，由于波长的不同，传输信号会产生畸变。建议构建系统的光纤组件(包括一个无线电光转换器)，以尽量减少这种失真。

The Propagation Model of Modulated Subterahertz Signals in the RoF Communication Systems

Radio-over-Fiber system scheme is described in the paper, the radio domain of this system is performed in the range 75–110 GHz (W-band). Optical signal with given orbital angular momentum (OAM signal) generation method in RoF fiber optic domain is suggested. The method is based on applying two independent lasers, performing at close wavelengths and the device for spatial phase modulation. For simulation and system parameters calculating, mathematical model of OAM signal envelope is suggested based on simplified wave equations system. Computer simulation of these signals envelope during its transmission was performed. It is shown that distortion of transmitted signals arises because of wavelengths difference. Recommendations were developed for constructing fiber-optic components of the system (including a radio-optical converter) designed to minimize this distortion.
