摘要
在分析ROF(radiooverfiber)系统组成与传输非线性的基础上,提出了用Volterra泛函级数为非线性ROF系统建立模型。研究了非线性ROF系统的Volterra级数表述、最小均方和最小二乘两种确定Volterra级数核的自适应算法在非线性ROF系统建模中的应用。通过一个用Volterra泛函级数对非线性ROF系统建模的实例,比较了VolterraLMS和VolterraRLS算法在建模中的效果,证明了用Volterra级数对非线性ROF系统建模的有效性。
After introducing the configuration and analyzing the nonlinear distortion of the radio-over-fiber （ROF） system, the Volterra series is proposed to model the system. In this paper, the ROF system is described with Volterra series, and the adaptive algorithm LMS and RLS for identify Volterra kernel are studied. A simulation is given, which use both Volterra LMS and Volterra RLS to model an nonlinear ROF system, and indicates that the method in this paper is efficient.
