Analysis of Diversity Reception for ATSC 3.0 Mobile Broadcasting Services

This paper examines Advanced Television System Committee (ATSC) 3.0 diversity reception in mobile broadcasting environments. Link-level simulations are conducted to assess error performance under vehicular reception scenarios. Considering practical real-world conditions, two distinct physical layer pipes (PLPs) are evaluated, representing services targeted for mobile and stationary services. These PLPs are characterized by their sub-carrier spacing, which determines resilience to Doppler effects. Additionally, this study highlights the performance gain achieved through maximal ratio combining (MRC) in ATSC 3.0 applications over the other diversity techniques, such as equal gain combining (EGC) and selection combining (SC). The results demonstrate the superiority of 4-antenna MRC, which is applicable to commercial vehicular receivers, across various channel conditions, including single-frequency network (SFN) and harsh mobile environments.
