Physical Layer Time Interleaving for the ATSC 3.0 System

An Overview of the ATSC 3.0 Physical Layer Specification

“…This case applies for single PLP (S-PLP), when LDM is used with a single PLP at each layer (the two PLPs are combined before the TI and hence they can be considered as one PLP), or for multiple PLPs (M-PLPs) with a constant cell rate transmission. The use of a CI for S-PLP doubles the time interleaving depth for a given memory size compared to a sheer block interleaver [20].…”

ATSC 3.0 Next Generation Digital TV Standard—An Overview and Preview of the Issue

“…The tenth paper [10], "Physical Layer Time Interleaving for the ATSC 3.0 System," by P. Klenner et al, presents the optimized time interleaver (TI) adopted for the ATSC 3.0 system as a physical layer tool to mitigate the effects of burst errors. The time interleaver is very flexible and can have different configurations according to the number of physical layer pipes and service type: sheer convolutional TI, twisted block TI, and hybrid TI composed of cell interleaver, twisted block interleaver, and a convolutional delay-line.…”

Layered Division Multiplexing With Multi-Radio-Frequency Channel Technologies

“…• A hybrid TI constituted by a joint cell and a twisted block interleaver (BI) for intra-frame TI, when there are multiple services per frame (M-PLP) [25]. Additionally, the DVB-NGH BI is also shown for comparison, since it is used for TFS operation in DVB-NGH [26].…”
