Performance assessment of the advanced time division multiple access system by simulation

This paper describes the structure of a simulator developed for the performance assessment of the advanced time division multiple access system. The simulator incorporates a resource allocator (RA) module which interacts with other subsystems in the ATDMA model such as medium access, link adaptation, dynamic channel allocation and ARQ, as well as long term processes such as handover and admission control. The paper deals with the queuing and prioritising functions of the ATDMA model and the practical limitations which must be incorporated within the simulator for realistic assessment of system performance.
