Performance evaluation of distributed Tarokh SFBC and Alamouti MISO for SFN DVB-T2 broadcast networks

Abstract

In this paper, we evaluate the performances of distributed Tarokh Space Frequency Block Coding (SFBC) compared to classical Single Frequency Network (SFN) and Distributed Alamouti MISO with SFN (MISO-SFN) for the emerging second generation digital TV Broadcasting (DVB-T2). We showed the performance of SFN and Alamouti MISO-SFN for two, three and four transmitters for DVB-T2 chain. We also compared the performances of distributed Tarokh MISO compared to SFN and Alamouti MISO-SFN for three transmitters in OFDM transmission with LDPC and BCH coding to be similar as DVB-T2 chain. The results showed clearly that the distributed Tarokh diversity can be used to improve the DVB-T2 network of three antennas and more.
