Abstract

Current paper characterizes the performance of the three-radio-frequency-channels, orthogonal-frequency-division-multiplexed (OFDM) radio-over-fiber (RoF) transmission system in terms of error-vector-magnitude and received optical signal power for a typical 10 GHz receiver obtained by the comprehensive simulations. The impact of the transmitted OFDM channels' signal-to-noise ratio (SNR) is also considered. We demonstrate that the SNR decrease from 40 dB to 25 dB results in an error vector magnitude (EVM) increase of up to 4 %. Furthermore, we propose the approach for allowing adjusting these results to other receiver sensitivity and responsivity values by introducing a delta in received optical signal power eliminating additional simulation or complicated calculations. The feasibility of the adjustments with a precision of up to 0.001% of the EVM is proved.

功率限制可调10G接收机参数的A-RoF传输

本文通过综合仿真，从误差矢量大小和典型10ghz接收机接收光信号功率两方面对三射频信道正交频分复用(OFDM)光纤无线电(RoF)传输系统的性能进行了表征。同时考虑了传输OFDM信道信噪比的影响。我们证明，信噪比从40 dB降低到25 dB导致误差矢量幅度(EVM)增加高达4%。此外，我们提出了一种方法，允许通过引入接收光信号功率的增量来调整这些结果以适应其他接收器灵敏度和响应度值，从而消除了额外的模拟或复杂的计算。结果表明，调整精度可达EVM的0.001%。
