- Abstract
- This paper presents performance comparison between layered division multiplexing (LDM) and time division multiplexing (TDM) based mobile services in the Advanced Television System Committee (ATSC) 3.0 standard. The comparison has been performed through extensive computer simulations, leveraging full-chain simulator entirely compliant with A/322. The simulation results demonstrate that LDM can significantly lower the signal-to-noise ratio (SNR) requirement compared to TDM in a given mobile scenario while maintaining the same (or analogous possible) data rate. For instance, LDM based mobile service is 6.1 dB more robust than TDM based service at a velocity of 100 km/h. In addition, even though LD M uses larger FFT size than TDM (16k-FFT for LDM and 8k-FFT for TDM), it is verified that LDM based mobile service is fully feasible under high speed condition.
