英文摘要：

To improve the reliability and validity of multi-input multi-output（ MIMO） communication system,Space-Time Block Codes（ STBC） has been widely used. This behavior has brought new challenges for MIMO communication. The blind classification of signals in MIMO-STBC communication systems,including blind estimation of the number of the transmit antenna,blind classification of the modulation type and blind classification of the STBCs,is the attractive research topic of signal processing in the last decade or more. Firstly,the research status of MIMO-STBC communication systems is introduced. Secondly,the main idea and method of MIMO-STBC communication is proposed. Finally,the development of MIMO-STBC is concluded. Simulations show that the proposed methods perform well and are suitable for practical application.
