Capacity optimization in systems with AMC

Capacity of systems using single modulation type can be calculated in a semi-deterministic fashion. However, for systems with adaptive modulation and coding, the capacity is also dependent on the distribution of modulations and traffic beneath these distributions. In order to utilise the network resources effectively, the areas with higher traffic should be covered with higher order modulation that can provide higher throughput levels. In this work, an optimization metric is proposed for utilization of the systems with adaptive modulations. The proposed metric, by making use of the coverage areas of specific modulations and the traffic demand beneath them; will be an important tool in the optimization procedures of systems that support multi-level modulations such as 3G and 4G.
