Authors propose to use cell level simulation as a natural follow up of the link level tests and a preliminary stage of the systematic approach to the system level tests in the context of IMT-Advanced candidates performance evaluation. The system under test (SUT) consists of flexible realizations of the WiMAX physical layer abstraction (providing customized(More)
The authors contribute to the spectrum of quality of experience (QoE) research by defining simulation platform for evaluation of VoIP quality of experience over a wireless WiMAX link. In particular the authors show how the Matlab/Simulink and ns2 integration can be facilitated to tackle the QoE aspects in a comprehensive manner. Furthermore the process of(More)
