Transmission scheme for the terrestrial ISDB system

Abstract

In Japan, the final draft specifications for a terrestrial digital broadcasting system called ISDB-T was fixed in September 1998 by the Association of Radio Industries and Businesses, and this paper describes the transmission scheme for that system. This transmission scheme can be sufficiently flexible and extendible. We propose the introduction of a frame structure to both the OFDM signal and the transport signal in order to provide hierarchical transmission flexibly while reducing the complexity of the receivers.
