本文介绍了地处山区某部运用750MHz邻频技术与单膜光纤传输技术、微波传输技术等三大手段,传输40套电视节目的设计思想与最终效果;重点介绍了开路信号与微波的接收、处理与传输。 我部是军内大型科研单位,地处川西北山区,四面环山,接收邻近城市的电视信号难度较大。经过我部技术人员与四川视达集团合作,使用750MHz邻频技术,传输40套节目成功。 This article describes the design concept and the final result of transmitting 40 sets of TV programs in a mountainous area using 750MHz adjacent channel technology, single-film optical fiber transmission technology and microwave transmission technology. The introduction of open-circuit signals and microwave reception, Processing and transmission. I Division is a large military research unit, located in the mountains northwest of Sichuan, surrounded by mountains, receiving television signals from neighboring cities more difficult. After my department technical staff and Sichuan Vision Group, 750MHz adjacent frequency technology, the transmission of 40 sets of successful programs.
