【摘要】 高副载波复用（ＭＳＣＭ）ＡＭ－ＶＳＢＣＡＴＶ系统在国内正日渐引起人们的关注。本文提出了采用掺铒光纤放大器（ＥＤＦＡ）和线性化外调制器在系统中进行优化，以实现高副载波复用。并首次采用定量的无约束数值优化法，即单纯形法，对全系统中一些关键参数进行优化，从而为ＭＳＣＭＡＭ－ＶＳＢＣＡＴＶ系统的优化设计提供了一种有实际意义的通用方法。更多还原

【Abstract】 An interest in MSCM AM VSB CATV system is rising in China. In this paper we presents using EDFA and linearized external modulation for microwave subcarrier multiplexed (MSCM) lightwave system. And we adopt quantitative unconstrained numerical optimization method(simplex method) to optimize some key parameters of the system for the first time. So we provide a general method for MSCM AM VSB CATV system optimization.更多还原
