摘　　要：面对广播电视移动化、交互化等的需求,在相关研究机构、厂商的推动下,3GPP组织在Release16版本进行了5G地面广播的标准化,成为了广播电视走向移动化的重要可选路径之一。本文通过理论推导、链路级仿真计算对比分析了不同信道条件下DTMB和5G地面广播的误码率、BICM传输效率、系统传输效率等指标,为广播电视无线传输技术的迭代分析提供指标参考。With the demand of radio and television mobility and interactivity,under the promotion of relevant research institutions and manufacturers,3GPP organization standardized 5G terrestrial broadcasting in Release16,which has become one of important alternative paths for radio and television to move towards mobility.This paper compares and analyzes bit error rate,BICM transmission efficiency,system transmission efficiency and other indicators of DTMB and 5G terrestrial broadcast under different channel conditions through theoretical derivation and link-level simulation calculations,which provides index reference for iterative analysis of radio and television wireless transmission technology.
