Abstract :
In this paper, we develop a novel analytical model to examine the coverage and capacity of MBSFN (MBMS over a single frequency network) OFDMA, proposed to deliver TV services to mobile users in forthcoming 3G LTE networks. First, analytical expression for SINR at a given point in a cell is derived, which takes into account the SFN gain and propagation delay values. Next, the shadowing effect of propagation on MBSFN is considered. In addition, dynamic MBSFN, an advanced MBSFN technique, in which the network cells are dynamically activated based on user traffic, is modelled. Finally, the performance of MBSFN is evaluated based on the proposed analytical model. This includes the investigation of MBSFN related parameters such as the modulation and coding scheme (MCS) values and the length of cyclic prefix, as well as the verification on the accuracy of the proposed model and the impact of shadowing. Dynamic MBSFN is also analyzed and we show its effect on the coverage for different traffic scenarios.
