MOBILE SYSTEM FOR SIGNAL INTERFERENCE CANCELLAION OF MULTI INPUT MULTI OUTPUT NETWORT

摘要

The present invention relates to a mobile communication system capable of removing signal interference in a multiuser MIMO network and provides the mobile communication system capable of effectively removing signal interference by detecting the signal with one detection method among a zero forcing (ZF) method, a minimum mean square error (MMSE) method, a successive interference cancellation (SIC) method and an ordered successive interference cancellation (OSIC) method by receiving a data stream pre-coded with a thomilson harashima precoding (THP) or dirty paper coding (DPC), and the relay node of an LTE mobile communication system is operated as an amplify and forward (AF) or a decoded and forward (DF) mode.
