Original Abstract

This short paper deals with the performance of the rotated constellation, which is one of the main innovations in the DVB-T2 (Second Generation Digital Terrestrial Television Broadcasting) standard. Rotated constellation is an optional feature to improve performance in frequency selective channels. This paper contains the present and progress results of the rotated constellation performance. For the determination of differences between the non-rotated and rotated constellation, a 0 dB Echo channel model was used. Graphical dependences of the BER before and after LDPC coding are given. Finally, achieved results are evaluated and discussed with promising expectations of a very good performance of rotated constellation technique in DVB-T2.
