TL;DR: The capability and limitations of the current LTE LTEMBMS system are studied, and potential physical-layer enhancements are investigated for futureMBMS systems to achieve enhanced broadcast service delivery capability, higher spectrum efficiency, improved service quality, and more efficient SFN deployment options.

TL;DR: Simulations demonstrate that, similar to the 4G long term evolution, the ATSC 3.0 co-channel assignment could be reduced to two times the service coverage radius, which means an improvement of the spectrum efficiency by up to four times in comparison with today’s system.

TL;DR: This paper studies possible physical layer enhancements to the Long Term Evolution (LTE) evolved Multimedia Broadcast Multicast Service (eMBMS) system to improve its spectrum efficiency and service quality using channel bonding of wide band Radio Frequency transmission, non-orthogonal multiplexing, and larger Cyclic Prefix duration and cell size.

TL;DR: This paper presents several channel estimation solutions at receivers to enable high-efficiency local content insertion within an ATSC 3.0 SFN and proposes a novel channel separation algorithm to significantly reduce the performance degradation caused by the inaccurate channel estimate due to the deterministic co-channel interference.

TL;DR: This paper discusses the ATSC 3.0 coverage and co-channel interference issues, using LDM technology with different operating parameters, to improve the coverage and reduce the interference.
