Technology for the next generation of digital terrestrial broadcasting : Transmission characteristics of 4096QAM-OFDM

Abstract

NHK is conducting research on the next generation of digital terrestrial broadcasting to enable large-volume content services such as Super Hi-Vision. We are studying on the large capacity transmission technologies using dual polarize MIMO and ultra multi-level OFDM. We have developed a prototype of MIMO-OFDM (4096QAM) modulator/demodulator that have large transmission capacity. We have conducted indoor and field experiment, and this paper describes the verification of transmission characteristics.
