Abstract :
Several DCA techniques have been proposed in the literature over the last few years, aiming to increase mobile cellular system capacity. The implementation complexity of those algorithms has motivated the conceptualisation and introduction of a new channel allocation technique named simplified maximum packing which offers a similar performance to the maximum packing technique presenting however a complexity reduction in terms of involved resources and signalling. Another aspect included in this paper is the formulation of a new mathematical model to evaluate the maximum packing technique performance based on multidimensional Markov chain theory. The values resulting from the analytical model give the theoretical performance limit of a technique that uses DCA concepts and could be extrapolated as representing the simplified maximum packing technique performance. The proposed mathematical model was validated via simulation for systems with different cell layouts, interference constraints, number of available resources and traffic load values
