本文在应用MFPP模型分析光接收机随机特性的基础上,用矩母函数对光通信系统抖动和接收机的最优化进行了探讨。1定时抖动分析下图给出了定时电路框图。图中随机过程X(t),Y(t),Z(t)都是圆平稳随机过程。非线性处理后输出过程Y(t)可分解为Y(t)=m_y(t)+Y_(sg)(t)+y_p(t)+Y_m(t)其中,m_y(t)为包含了定时信息的周期性信号;y_(sg)(t)为散弹噪声和热噪声混合贡献项(简单定时提取时可分为单独两项);Y_p(t)为图案噪声项,只与图案随机性有关;Y_m(t)是混合噪声
Based on the analysis of random characteristics of optical receiver using MFPP model, this paper discusses the jitter of optical communication system and the optimization of receiver with the function of moment matrix. 1 timing jitter analysis The figure below shows the timing circuit block diagram. The random processes X (t), Y (t), Z (t) in the graph are all round stationary random processes. The nonlinear output Y (t) can be decomposed into Y (t) = m_y (t) + Y_ (sg) (t) + y_p (t) + Y_m (t) (Sg) (t) is the mixed contribution of shot noise and thermal noise (simple timed extraction can be divided into two separate items); Yp (t) is the pattern noise term, which is only related to the pattern randomness Y_m (t) is mixed noise
