The SFN Gain in Non-interfered and Interfered DVB-H Networks

The single frequency network mode (SFN) is one of the benefits of DVB-H network. In addition to the possibility to use only one frequency in given area, the reception of the same contents via two or more radio paths provides with SFN gain which enhances the quality of service whenever the respective sites are located inside the SFN limits. If the same frequency is used outside the theoretical SFN area, the sites that exceed the relative guard distance converts as interfering sources. This paper describes a simulation method for the investigation of the SFN gain in non-interfered network as well as in the environment with SFN interferences. Also simulation results and analysis with the most logical network parameter set is presented.
