摘　　要：NHK科技实验室在2014年1月的8K超高清地面电视广播传输试验中实现了以超高频谱效率(约16.5 bit/(s·Hz))远距离(约27 km)传输8K超高清电视节目,取得该巨大成功的关键在于其正在研发的用于下一代地面数字电视广播系统的大容量无线传输技术。对其中的大容量无线传输技术进行综述性介绍。It is confirmed that in January 2014, NHK Science ＆ Technology Research Laboratories has managed to send the 8K UHDTV terrestrial broadcasting signal to a receiving station 27 km away with super high spectrum efficiency of approximately 16.5 bit/（s· Hz）. Behind this hig success is the large-capacity wireless transmission technology on which NHK is conducting research and development. In this paper, these technologies are summarized.
