高频运行的高容量光纤无线通信系统越来越依赖射频信号的光子产生。在这些系统中，光信号通过光纤传输并由光电探测器检测，其中射频信号在等于光载波频率之差的频率上产生。一个主要的性能限制损伤是所产生射频信号的相位噪声，其源于光源的相位噪声。本文为采用光子射频产生的光纤无线通信系统的两种主要配置开发了综合概率模型。基于这些模型，我们提出了一种计算信息速率（IR）的有效数值框架。进行了数值模拟以验证所提算法的效率，结果为高性能光纤无线系统提供了设计指南。

英文摘要

High-capacity fiber-wireless communication systems operating at high frequencies increasingly rely on photonic generation of radio-frequency (RF) signals. In these systems, optical signals are transmitted over optical fibers and detected by photodetectors, where RF signals are generated at frequencies equal to the difference between the optical carrier frequencies. A major performance-limiting impairment is the phase noise of the generated RF signals, which originates from the phase noise of the optical sources. In this paper, we develop comprehensive probabilistic models for the two principal configurations of fiber-wireless communication systems employing photonic RF generation. Based on these models, we propose an efficient numerical framework for calculating the information rate (IR). Numerical simulations are performed to validate the efficiency of the proposed algorithm and the results provide design guidelines for high-performance fiber-wireless systems.
