Abstract

This paper presents a novel concept for offering payload resources flexibility in High Throughput Satellite (HTS) systems. The concepts makes joint use of two advanced techniques, namely beam hopping and precoding. The combination of these two techniques allows the system to really optimize the performance of beam hopping in terms of capability to follow the temporal and spatial variation of user traffic requests within the coverage. The performance of such an approach is demonstrated through computer simulations of an exemplary system. A similar approach can also be used by combing precoding with frequency flexible techniques. Additional combination of on-board power pooling techniques helps to further improve the system performance.
