Abstract:
SATELLITE communications will play a central role towards fulfilling next generation 5G communication requirements, As a matter of fact, anytime-anywhere connectivity cannot be conceived without the presence of the satellite segment.
In order to deliver broadband interactive data traffic, satellite payloads are currently implementing a multibeam radiation pattern. The use of amultibeam architecture brings several advantages in front of a single global beam transmission.
First, since an array fed reflector is employed, the antennagain to noise ratio can be increased leading to high gain of each beam return link achievable throughput. Second, different symbols can be simultaneously sent to geographically separated areas, allowing a spatially multiplexed communication.
In this paper, we study the pre-coding algorithms (beamforming) used to secure a multi-beam system, and compare them, as well as the importance of scheduling users within the same framework.
