SIGNAL TRANSMISSION METHOD USING CONSTELLATION REARRANGEMENT IN RELAY SYSTEM

摘要

PURPOSE: A signal transmission method using constellation rearrangement in a relay system is provided to reduce the reliability difference between bits constituting signal points. CONSTITUTION: A transmission terminal transfers a signal to plural relay nodes, and the plural relay nodes maps the transferred signal to constellation. The plural relay nodes transfer the mapped signal to the reception terminal. The transmission terminal combines the mapped signals with the constellation received from the plural relay nodes.
