On the performance of the dvb-t system in mobile environments

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 DVBT specifications. Rather, it is the lack of time interleaving that might pose problems.
