- Abstract
- This paper presents a new decoding scheme of emergency alert (EA) wake-up bits and evaluates its decoding performance in Advanced Television Systems Committee (ATSC) 3.0. Given that the minimal essential information in the bootstrap signal of ATSC 3.0 is not being changed often, the received signal can be further assumed to be binary modulated according to each wake-up bit. Therefore, the wake-up bits can be obtained independently regardless of other signaling information after the initial decoding that obtains entire information carried by the bootstrap. The simulation results show that the proposed decoding scheme of wake-up bits outperforms the conventional scheme which decodes the entire information carried by the bootstrap.
