广播电视微波电路传输通道保护技术

Transmission Channel Protection Technology of Radio and Television Microwave Circuit

随着我国广播电视的快速发展,电视节目的传送方式趋向数字化。通过改进微波传输通道的保护宽度,提高信号传输的实际精度,建立SDH设备互联传输,实现广播电视网元的统一管理,提出广播电视微波电路传输通道保护技术,该种技术具有良好的AIS比特率,保护性能更加可靠。

With the rapid development of Chinese Radio and television industry,there is a digitalize trend for the transmission mode of various TV.To ensure the stable transmission and broadcasting of radio and television,the transmission channel protection technology of radio and television microwave circuit is proposed.By improving the protection width of microwave transmission channel,the actual accuracy of signal transmission is improved;establishing SDH equipment interconnection transmission to realize the unified management of radio and television network elements;diversity receives the transmission signal to reduce the weakness of microwave circuit in transmission.The experimental results show that this microwave circuit channel protection technology has better AIS bit rate and more reliable protection performance for the microwave circuit transmission channel.
