    摘要:

    DVB-T2为DVB-T的升级标准,采用了一系列宽带无线通信领域的先进技术,不仅提供了优质音视频服务,也为外辐射源雷达提供了新型照射源。本文针对DVB-T2信号的结构特点,提出了适应DVB-T2系统的参考信号重构方法。首先研究了基于P1符号的双相关算法,使同步结果更加精确;然后提出二维线性插值的信道估计算法。实测数据验证了该算法能够改善参考信号的重构质量。

    Abstract:

    DVB-T2 is an upgraded standard of DVB-T, it adopts a series of advanced technologies in the field of broadband wireless communication, which not only provides high-quality audio and video services, but also provides a new type of radiation source for passive radar. According to the structural characteristics of DVB-T2 signal, this paper proposes a reference signal reconstruction method adapted to DVB-T2 system. Firstly, the dual correlation algorithm based on the P1 symbol is studied to make the synchronization result more accurate,then a channel estimation algorithm based on two - dimensional linear interpolation algorithm is proposed. The measured data verify that the algorithm can improve the reconstruction quality of the reference signal.
