Abstract

NHK is conducting research on the next generation of digital terrestrial broadcasting to enable large-volume content services such as Super Hi-Vision (8K). In a previous study on dual-polarized MIMO transmission, we used low density parity check (LDPC) code for forward error correction (FEC) and developed a multi-dimensional interleaving scheme that reduces deterioration caused by the difference between the channel responses of both polarizations. In this study, we developed a decoding algorithm for LDPC code that iteratively uses the channel responses of dual-polarized MIMO transmission for the log likelihood ratio (LLR) calculation, and tested it in a computer simulation.
