Abstract

DVB-T2 is an emerging terrestrial digital video broadcasting standard. Compared to DVB-T, which is widely deployed at the present time, DVB-T2 promises performance gains because of improved coding, modulation and multiple antenna technologies. Alamouti Space-Frequency coding in DVB-T2 provides additional frequency diversity, especially in multipath propagation environments. Coding and interleaving is done with sufficient depth such that temporal diversity can be exploited as well. In this paper we investigate the achievable diversity gains, which can achieved by the application of the diversity techniques the DVB-T2 standard offers in addition to standard conformable transmit antenna technologies. Simulations for a specific DVB-T2 parameter set have shown that there is a potential gain in SNR of 9dB.
