Design and analysis of hybrid approach to mobile TV service over WiMAX network

In this paper, we propose a novel mobile TV service over WiMAX network. Instead of using broadcasting method or unicasting scheme, we use a hybrid approach that exploits adaptive modulation and coding (AMC) gain in unicast scheme and at the same time accommodates arbitrary many users watching the same channel like broadcast method, which enables to increase wireless capacity for mobile TV service. In addition, we present a WiMAX design tool, based on an analytical model, maximizing WiMAX capacity and study the influence of the most important traffic and system parameters. The analytical model can provide an accurate estimate of the amount of bandwidth for WiMAX TV service.
