地面数字电视广播单频系统,是我国广播电视的重要部分,而单频网作为传输覆盖工程最为常见的应用方法之一,不但能够实现频率规划的高效性,还能够实现多点射频来解决覆盖过程的盲区问题,极大地提高地面数字电视广播单频网进行传输覆盖工程的覆盖率。并且,单频网络能够实现辐射低、覆盖均匀、污染小的性能,具有良好的效果。 Terrestrial digital television broadcasting single-frequency system is an important part of China’s radio and television, and single-frequency network as the transmission coverage project is one of the most common application methods, not only to achieve the efficiency of frequency planning, but also to achieve more RF to cover coverage Process of blind spots, which greatly improve the terrestrial digital television broadcasting frequency coverage for transmission coverage project. And, single-frequency network can achieve low radiation, uniform coverage, small pollution, with good results.
