Abstract

Mobile multimedia services may become an important feature of terrestrial networks for a variety of applications. One possible scenario to offer digital TV services for mobile and portable receivers is to use the European DVB-T specifications that may allow high data rate transmission in an 8 MHz UHF channel. Although the DVB-T specifications were designed for fixed reception, some of its robust modes might allow mobile reception of TV-services. We analyse by means of theoretical investigations, computer simulations, laboratory tests and field trials, the behaviour and limits of the DVB-T specifications in mobile environments. Here, it seems that the Doppler shift is not necessarily the fundamental limitation of the DVB-T specifications. Rather, it is the lack of time interleaving that might pose problems.
