摘要
在目前高科技信息化时代背景下,我国的调频广播工作正面临着新的机遇和挑战。由于我国的音频信号是通过直射波传播的,自然环境和通讯设备等因素比较容易对传播信号的质量产生影响,因此,对调频广播覆盖的覆盖效率进行优化具有十分重要的意义。文章首先对影响调频广播覆盖的发射源因素、电磁因素和地理因素进行了分析,然后分析了调频广播覆盖的优化技术,提出应该从选取适宜的发射机功率、对发射天线进行合理的选择和安装、利用调频同步广播技术等方面对调频广播的覆盖进行优化,以期为同行提供参考。
Firstly,the source of emission factors FM radio coverage,electromagnetic factors and geographical factors are analyzed,and then the FM broadcast coverage of optimization techniques were analyzed,should be selected from the appropriate transmitter power, antenna to transmit a reasonable choice and installation,the use of technology and other aspects of FM simulcast on FM radio coverage be optimized in order to provide reference for the peer.
