Optimal linear precoding scheme for multibeam satellite systems based on partial channel information

Hybrid Full Frequency Precoding for Integrated Remote Wireless Sensor and Multibeam Satellite Networks

“…[26] studied the optimization of linear precoding for MSNs with general linear and nonlinear power constraints, the proposed methods also could be applied to processing in satellite. [27] employed the Shadowed-Rice fading channel model and derived an approximate outage capacity expression for the multibeam mobile satellite system. However, the MIMO precoding assumed that one terminal was served per beam for each time slot by employing time division multiplexing (TDM), and explicitly stated that a set of terminals were served per beam for each time slot as an open problem to be studied [25]- [27].…”

Precoding for MSNs in the existing research mainly considered throughput maximization as the optimization objective, while TPM problem and MMF problem are the hot research area in the WSNs [20] [21] and MIMO systems [28]- [31].…”
