Transmission technology for the next generation of digital terrestrial broadcasting : A study on bit interleaving in dual polarized MIMO transmission

Abstract

NHK is conducting research on the next generation of digital terrestrial broadcasting to enable large-volume content services such as Super Hi-Vision. In dual polarized MIMO transmission, we applied LDPC (Low Density Parity Check) code to FEC (Forward Error Correction), and previously reported a multi-dimensional interleaving scheme that reduces deterioration caused by the difference of channel responses of two polarizations. We developed the bit interleaving scheme that is applied in multi-dimensional interleaving and dual polarized MIMO transmission, and this paper reports the result of computer simulation.
