Already DVBs first generation terrestrial broadcasting standard – DVB-T – enables the mobile reception of digital services. However, since the development of DVB-T in 1995 there have been significant improvements in the area of signal processing algorithms and semiconductor manufacturing. Hence, DVB initiated the development of a second generation terrestrial transmission standard that has been finalized 2008, i.e. DVB-T2. Using state-of-the-art algorithms this standard reaches the theoretical limits quite close and offers increased flexibility for all kinds of broadcast scenarios. A special focus was put on the performance in mobile reception. The use of an optimized forward error correction in addition to MIMO techniques offers reliable data transmission, also in difficult channels. This article will describe the key features of DVB-T2 enabling robust mobile reception, and in addition, will show simulation results in different mobile channels and reception scenarios.
