广电网络中短波发射抗干扰技术

Anti-Jamming Technology of Short-Wave Transmission in Broadcasting Network

广播电视是传递信息、文化和娱乐的重要手段,尤其在一些偏远地区和紧急灾害事件中起着重要作用。保证广播电视信号的传输可靠性,对于人们的信息获取和社会稳定具有重要意义。但实际上在广电网络运行中,短波发射台面临来自各种干扰信号的挑战,包括电磁干扰、频谱干扰、周边设备干扰等,这些干扰可能导致广播电视信号的失真、丢失,影响传输质量和接收效果。因此,有必要通过抗干扰技术来减少外界干扰信号对广播电视信号的影响,提高频谱资源的利用效率。基于此,就广电网络中短波发射抗干扰技术进行研究,以期为广电网络的运行质量提供坚实保障。

Radio and television is an important means of transmitting information,culture and entertainment,especially in some remote areas and emergency disaster events play an important role.Ensuring the transmission reliability of radio and television signals is of great significance to people's information acquisition and social stability.However,in fact,in the operation of radio and television network,the short-wave transmitter faces challenges from various interference signals,including electromagnetic interference,spectrum interference,peripheral equipment interference,etc.,which may lead to the distortion and loss of radio and television signals,affecting the transmission quality and receiving effect.Therefore,it is necessary to reduce the influence of external interference signals on broadcast and television signals by anti-interference technology and improve the utilization efficiency of spectrum resources.Based on this,this paper studies the anti-interference technology of short-wave transmission in radio and television network,in order to provide a solid guarantee for the operation quality of radio and television network.
