초록
This paper investigates the performance gain of additional parity which can be employed for improving the robustness of physical layer [layer-1 (L1)] signaling (L1 signaling) in Advanced Television Systems Committee (ATSC) 3.0. Its performance gain is evaluated in the view point of additional coding gain and diversity gain with extensive computer simulations. We first evaluate the coding gain with the aid of capacity analysis over AWGN channel, and then the diversity gain is evaluated over TU-6 channel based on the ATSC 3.0 frame structure. Numerical results show that additional parity gives significant performance gain under mobile environments.
