A single-chip band-segmented-transmission OFDM demodulator for digital terrestrial television broadcasting

In Japan, Digital Terrestrial Television Broadcasting (DTTB) is to be launched in 2003. Although this launch is several years later than in the U.S. and Europe, it has features capable of accommodating a variety of broadcasting services. These features include, for example, flexible use of transmission capacity and robust mobile reception, in addition to common services such as high-definition TV (HDTV) and multiple standard definition TV (SDTV). To meet these requirements, DTTB in Japan has adopted orthogonal frequency division multiplexing (OFDM) with band segmented transmission for modulation and multiplexing. This single-chip OFDM demodulator, offers a variety of services, such as multi-layer transmission and mobile reception.
