RELIABLE CHANNEL STATE INFORMATION IN MULTI-BEAM SATELLITE COMMUNICATIONS

摘要

The invention provides a method for determining the reliability of estimated channel state information for each carrier/beam in a multi-beam satellite communication system, wherein the 5 signals are transmitted using aggressive frequency reuse among the carriers/beams. The proposed method allows to reduce the complexity of the receiver as compared to known systems, as the detection of interfering carriers is shifted towards the end of the workflow, when the signal of the reference carrier has already been frequency, phase, and time compensated.
