Layered-Division-Multiplexing (LDM) technology has been shown to provide significant performance improvent for digital TV (DTV) broadcasting systems to simultaneously deliver a robust mobile TV service and one or more high-throughput fixed services in the same 6 MHz TV channel. So far, the focus of LDM for future DTV systems has been put on delivering mixed mobile and fixed services since this is...
As the next generation digital TV (DTV) standard, the ATSC 3.0 system is developed to provide significant improvements on the spectrum efficiency, the service reliability, the system flexibility, and system forward compatibility. One of the top-priority requirements for the ATSC 3.0 is the capability to deliver reliable mobile TV services to a large variety of mobile and indoor devices. Layered-division-multiplexing...
One of the top-priority requirements for the next generation digital TV (NG-DTV) system is the capability to deliver robust services to both mobile and fixed receivers under challenging propagation conditions. One typical challenging scenario is indoor reception, where the penetration loss could be as high as 20 dB. Other challenging scenarios include outdoor mobile reception at various receiver speeds,...
Layered-Division-Multiplexing (LDM) technology is a non-orthogonal multiplexing (NOM) technology which enables efficient transmission of multiple signals with different robustness and throughput requirements. By performing efficient noise filtering, DFT-based channel estimation (DFT-CE) method has been shown to be able to provide near-optimal performance with low complexity in a Typical Urban (TU)...
