Hardware Implementation and Complexity Analysis of Layered Division Multiplexing (LDM) System for ATSC 3.0

摘要

This paper proposes a novel low complexitylayered division multiplexing (LDM) transmitter andreceiver structure for the Advanced Television SystemsCommittee (ATSC) 3.0 system, and analyzes its performancethrough computer simulation and hardware laboratory test.The proposed low complexity LDM system not only showssignificant performance gain (3 to 9 dB) compared totraditional TDM system, but also supports up to the velocityof 260 km/h (@ CH. 50) in case of mobile reception.
