为了支持新兴的交互式服务，已经达成共识，包括一个可选的，带内专用返回信道（DRC）的下一代地面广播系统（ATSC 3.0）。本文介绍了DRC的设计以及实现的几个问题。首先，详细描述了DRC的网络结构、链路预算和辐射特性。然后分别对DRC的物理层和MAC层进行了需求分析和详细设计。同时，DRC的性能进行了评估，并与典型的技术进行了比较，在误码率，接入概率，资源利用率等，此外，下行广播和DRC之间的合作进行了分析。
To support emerging interactive services, a consensus to include an optional, in-band dedicated return channel (DRC) for the next-generation terrestrial broadcast system (ATSC3.0) has been reached. This paper introduces the design of DRC as well as several implementation concerns. First, the network architecture, link budget, and radiation feature of DRC are described in detail. Then the requirements and detailed design of both the physical layer and the MAC layer of DRC are presented respectively. Meanwhile, the performance of DRC is evaluated and comparisons with typical techniques are carried out in terms of bit error rate, access probability, resource utilization, etc. Furthermore, the cooperation between downlink broadcast and DRC is analyzed.
