PROJECT TITLE :

Physical Layer Time Interleaving for the ATSC 3.0 System

ABSTRACT:

This paper presents optimized time interleaving which has been adopted for the Advanced Television System Committee 3.0 system as a physical layer tool to mitigate the results of burst errors. The adopted time interleaver (TI) is terribly flexible and can have completely different configurations per the amount of physical layer pipes (PLPs) and service kind, i.e., fastened, portable, and mobile. Notably, for single-PLP mode a sheer convolutional TI (CTI) is employed, whereas for the multiple-PLP mode a hybrid TI (HTI) composed of cell interleaver, twisted block interleaver, and a convolutional delay-line is used. Optionally, the CTI and also the HTI will be used in conjunction with extended time interleaving and a cell interleaver (only for HTI) to additional improve robustness over long burst error lengths at the expense of latency.
