Within modern satellite communication scenarios, different users demand different bandwidths. Hence, digital processors should allow for flexible processing of FDM-signals for meeting these requirements. In that scope, two mutually exclusive processor tasks are distinguished: i) mere demultiplexing of independent FDM-signals and ii) demultiplexing of(More)
The competitiveness of the satellite in access communication systems is today more and more threatened by the considerable continuous progress seen in terrestrial fixed and wireless communications networks. Nevertheless satellites still represent an attractive solution for broadcasting, multicasting and point-to-point communications, because of their(More)
This paper presents a novel digital MIMO filter bank technique for modern broadband multibeam communcations satellite systems, which efficiently exploit available bandwidth by providing different users with different bandwidths for different types of services. This necessitates a flexible and dynamic resource reallocation, where the assumed traffic is(More)
Modern satellite communication calls for novel and flexible concepts for deand remultiplexing of wide-band FDM-signals in conjunction with beam switching on-board a satellite. For this application, two highly efficient approaches to uniform and yet reconfigurable digital filter banks are known: i) the complex-modulated polyphase filter bank, and ii) the(More)
