Communication on the Move with Satellite Digital Beamforming
Abstract
Existing communications systems have typically been designed to serve users with the maximum possible signal-to-interference-plus-noise ratio (SINR) or the highest data rate that is independent of user demand and the environment. This may not be necessary in practice, and it may not be smart to waste limited resources such as bandwidth and power. The objective of this project is to study efficient satellite digital beamforming (BF) methods by which satellite can provide the user-specific desirable SINR or data rate to user who is on the move under various levels of jamming powers in dBW and interference from adjacent satellites. For example, user k may want a low SINR because his communication link is in a good channel condition and he simply wants to send a voice signal, whereas user l may need a high because his communication link is in a bad channel condition and he wants to send a high data rate signal such as a video signal. Relative to these various channel environments and service demands, the objective of this project is to study methods for how a satellite supplies a user-dependent service.
