Modeling and Performance Evaluations of Alamouti Technique in a Single Frequency Network for DVB-T2
Alamouti space - frequency coding provides additional frequency diversity, especially in multipath propagation environments. This paper addresses a new modeling of the Alamouti code Multiple Input Single Output (MISO) in a Single Frequency Network (SFN) for two, three, and four transmitters, and different types of coding and modulations in the DVB-T2 (Digital Video Broadcasting Terrestrial second generation). Classical SFN, Alamouti MISO, and combined SFN with Alamouti MISO (called SFN-2x1 Alamouti MISO) are compared and analyzed. Performance evaluations are made for two, three, or four transmission antennas through 0-dB Echo profile, TU6 mobile channel, unbalanced received power and rotated constellation.
