Partial CSI based Regularized Zero-Forcing Precoder for Multibeam Satellite Communications toward 6G Networks
12TH INTERNATIONAL CONFERENCE ON ICT CONVERGENCE (ICTC 2021): BEYOND THE PANDEMIC ERA WITH ICT CONVERGENCE INNOVATION（2021）
摘要
Multibeam satellite communications have attracted attention as a potential solution to provide non-terrestrial networks (NTNs) toward 6G systems. In this paper, we study the partial channel state information (CSI) based regularized zero-forcing precoder to lessen the latency and signaling overhead for CSI acquisition while guaranteeing the achievable performance at low signal-to-noise ratio (SNR) region.
