摘要
随着地面数字电视技术的发展,多径干扰、频率干扰及电磁干扰等因素对数字电视信号的质量产生了明显影响,导致地面数字电视的正常传输和接收效果受损。为了提升地面数字电视信号的抗干扰能力,探讨信号调制、抗干扰编码技术、智能天线与频谱管理等多种有效技术手段,为优化地面数字电视信号的抗干扰技术提供理论依据。
With the rapid development of terrestrial digital television technology,the anti-interference ability of digital television signals has become a key issue in ensuring the quality of television signals and the viewing experience of viewers.Factors such as multipath interference,frequency interference,and electromagnetic interference have a significant impact on signal quality,seriously affecting the normal transmission and reception of terrestrial digital television.In order to enhance the anti-interference capability of terrestrial digital television signals,this article explores various effective technical methods based on signal modulation,anti-interference coding technology,smart antennas,and spectrum management,providing theoretical basis for optimizing the anti-interference technology of terrestrial digital television signals.
