Performance evaluation for different MISO - SFN network combinations for DVB-T2 standard

In this paper, we evaluate and compare the performances of different network combinations from the usage of coded MISO (Multiple Input Single Output) in a Single Frequency Network (SFN) for DVB-T2. We address classical SFN and different MISO-SFN network combinations. We mean by different combinations, the organization and position of antennas where some of them transmit the same symbols and others transmit modified symbols as defined by the DVB-T2 standard for Alamouti MISO. The number of combinations depends on the number of transmitters. Evaluations of the path loss are also given in this paper. We also propose an additional table of these combinations in the T2-Gateway. The simulations are done for three and four transmitters where there are four combinations for three transmitters and eight combinations for four transmitters. The results show clearly that the performances of the received signals depend on the network combinations and the difference can be higher than 2 dB.
