The most recent standard for broadcast services, Advanced Television System Committee—Third Generation (ATSC 3.0), has adopted co-located multi-antenna schemes and Layered Division Multiplexing (LDM) in order to increase the capacity and reliability compared to former Digital Terrestrial Television (DTT) systems. ATSC 3.0 has adopted both technologies separately, but no combination of them is planned yet. Compared to baseline LDM case, use of several antennas allows for diverse parametrization for each layer. This paper analyzes the potential combination of co-located Multiple-Input–Multiple-Output (MIMO) schemes with LDM. A trade-off analysis between complexity constraints and performance benefits is evaluated.

分层多路复用与协同定位的多输入多输出方案

广播服务的最新标准，第三代高级电视系统委员会 (ATSC 3.0)，采用了同地多天线方案和分层多路复用 (LDM) 以提高与以前的数字地面电视相比的容量和可靠性(DTT) 系统。ATSC 3.0 分别采用了这两种技术，但尚未计划将它们结合起来。与基线 LDM 情况相比，使用多个天线允许对每一层进行不同的参数化。本文分析了协同定位多输入多输出 (MIMO) 方案与 LDM 的潜在组合。评估复杂性约束和性能优势之间的权衡分析。
