Evaluation of Non-Uniform Constellations for the Converged Network of Broadcast and Broadband

Abstract

Broadband and Broadcast converged network is under investigation. Non-uniform Constellation (NUC) is one of the advanced technologies in the broadcast physical layer (adopted in ATSC3.0 and DVB-NGH). However, there are different voices in the broadband community regarding the implementation of NUC in 5G and beyond broadband wireless systems. In this paper, many different cases and scenarios are simulated to demonstrate that NUCs can provide performance gains and have positive impact to a converged network. Results show that the NUC could be considered as a promise technology for high data rate fixed services in the converged broadband wireless network.
