In the context of heterogeneous networks, femtocells are very promising. In order to properly simulate their behavior and their impact on the macrocell layer, it is necessary to be able to simulate the radio coverage of femtocells. Hence ParFlow is a possible deterministic model that can be used for such simulation. In this paper two implementations of ParFlow are presented: time domain and frequency...
To overcome interference, OFDMA networks support different but fixed frequency reuse schemes and subchannel allocation techniques. However, these fixed schemes and techniques are not the most suitable solutions in mobile scenarios, where the behaviour of the channel and the users are continuously changing during the day-time. This paper presents a new approach to the frequency assignment problem adapted...
