  Abstract

In various countries, the development and standardization of next-generation terrestrial broadcasting systems for transmitting digital broadcasting contents having ultra high definition (UHD) quality are underway. The North American standardization organization, Advanced Television Systems Committee (ATSC), has established ATSC 3.0, the next-generation digital broadcasting standard. Although ATSC 3.0 includes a two-layer layered division multiplexing (LDM) system and 2×2 multiple-input multiple-output (MIMO) system, it is necessary to increase additional transmission capacity for 8K-UHD TV. This paper describes a three-layer LDM-MIMO system made by combining a three-layer LDM system and MIMO technology to increase transmission capacity. Through simulation, the reception performance of each layer of the system according to a pilot pattern for channel estimation and a pilot signal interpolation method is analyzed. Simulation results show that the lower layer targeting fixed reception has excellent performance with the use of the Walsh Hadamard - discrete Fourier transform (WH-DFT) method, and the upper layer and middle layer targeting mobile reception have excellent performance for the WH-Linear method.
