DVB-RCS return link Radio Resource Management for Broadband Satellite systems using fade mitigation techniques at Ka band

Abstract

Current broadband satellite systems supporting DVB-RCS at Ku band have static physical layer in order not to complicate their implementation. However at Ka band frequencies and above an adaptive physical layer wherein the physical layer parameters are dynamically modified on a per user basis is necessary to counteract atmospheric attenuation. Satellite radio resource management (RRM) at the medium access control (MAC) layer has become an important issue given the emphasis placed on quality of service (QoS) provided to the users. The work presented here tackles the problem of Satellite RRM for broadband satellite systems using DVB-RCS where a fully adaptive physical layer is envisaged at Ka band frequencies. The impact of adaptive physical layer and user traffic conditions on the MAC layer functions is analyzed and an algorithm is proposed for the RRM process. Various physical layer issues associated with the resource management problem are also analyzed.
