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。
High subcarrier multiplexing (MSCM) AM-VSBCATV system is attracting people’s attention in China. This paper presents the use of erbium-doped fiber amplifier (EDFA) and linearized external modulator in the system to optimize in order to achieve high subcarrier multiplexing. And for the first time using quantitative unconstrained numerical optimization method, that is simplex method, to optimize some of the key parameters in the whole system, thus providing a practical method for the optimization design of MSCMAM-VSBCATV system.
