| Abstract: | A practical space time block coded(STBC) cooperative system is investigated.How a time-division-duplex based cooperative mode and the large scale path loss affect the diversity gain,the outage probability performance and the capacity of a cooperative system is analysed,then two criteria for selecting proper cooperative partner are discussed.Performance analysis and numerical results show that the STBC cooperative system is superior in some practical scenarios. |
