複数の送信先によって受信される干渉を制限する方法及びデバイス

Japanese Patent JP5779462

B2

The present invention concerns a method for limiting interference received by a plurality of destinations, the interference being generated by plural flows of complex modulation symbols transferred by a plurality of sources on same resources of a wireless telecommunication network. The method comprises the steps executed by a relay of : - receiving complex modulation symbols, - decoding complex modulation symbols and successfully retrieving an information word from which the complex modulation symbols are derived, - generating complex modulation symbols that will be transmitted by the source, - pre-coding the generated complex modulation symbols by a pre-coding matrix, the pre-coding matrix being defined so as to reduce the interference generated by the flow of complex modulation symbols on the other flows of complex modulation symbols, - transferring the pre-coded complex modulation symbols.
