This paper presents the work conducted as part of doctoral research carried out at ISAE and ONERA on dynamic Radio Resource Management techniques for DVB-RCS systems using Fade Mitigation Techniques at Ka band. For a system using Adaptive Coding and Modulation at its physical layer the problem of optimally apportioning the satellite carriers' among the many different waveforms, or modes, available becomes crucial to its efficiency. In current DVB-RCS systems the carriers' waveforms are defined during system design. In this work a process to dynamically define carrier waveforms during system operation, based on prevailing traffic and propagation conditions, is proposed whereby the system available capacity, and QoS are shown, via simulations, to improve compared to a static definition.
