MMDS的基本技术特点 1、采用残留边带调幅制式 在技术上多路多点分配系统MMDS(Multichannel Multipoint Distribution System)最基本的特点之一是沿用了地面电视广播的残留边带调幅(VSB-AM)制式,因而可采取下变频和电缆分配入户接收方式,用现在的家用电视接收机收视。
The basic technical characteristics of MMDS 1, the use of residual sideband AM system in the technical multi-channel multi-point distribution system MMDS (Multichannel Multipoint Distribution System) one of the most basic features is the use of terrestrial television broadcast sideband amplitude modulation (VSB-AM ) Standard, which can take down-conversion and cable distribution at home reception, with the current home TV receiver ratings.
