论文摘要
分析表达式是针对Wiener滤波器（WF）（也称为线性最小平方误差（LMMSE）估计器）的分析表达式，用于强度调节/直接检测（IM/DD）短-HAUL光纤通信系统。该链接纯粹是分散的，非线性方law检测器（SLD）在热噪声极限下运行。与忽略SLD的WF相比，通过考虑SLD来大大提高了几何形状的PAM星座的可实现速率。
Analytic expressions are derived for the Wiener filter (WF), also known as the linear minimum mean square error (LMMSE) estimator, for an intensity-modulation/direct-detection (IM/DD) short-haul fiber-optic communication system. The link is purely dispersive and the nonlinear square-law detector (SLD) operates at the thermal noise limit. The achievable rates of geometrically shaped PAM constellations are substantially increased by taking the SLD into account as compared to a WF that ignores the SLD.
