This paper audits the output carrier-to-noise ratio of a single-loop OEO when the incoming signal is contaminated with additive white Gaussian noise. Investigations have been carried out for the possibility of increasing the output carrier-to-noise ratio. A detailed analysis of the hysteresis or ‘jump phenomenon’ of the single-loop OEO has been reported by utilizing the Lyapunov stability criterion. The total output distortion power has been derived assuming Carson’s rule for bandwidth to hold, at the input port of the OEO. It has been observed that the injection synchronized OEO acts as an amplifier when the incoming FM signal is contaminated with noise.

加性高斯白噪声对 OEO 输出的影响

当输入信号被加性高斯白噪声污染时，本文审核了单回路 OEO 的输出载噪比。已经对提高输出载噪比的可能性进行了调查。已经利用李雅普诺夫稳定性准则对单回路 OEO 的滞后或“跳跃现象”进行了详细分析。假设在 OEO 的输入端口处保持带宽的卡森规则，已导出总输出失真功率。已经观察到，当传入的 FM 信号被噪声污染时，注入同步 OEO 充当放大器。
