APPARATUS AND METHOD FOR ENCODING/DECODING PSEUDO ORTHOGONAL SPACE TIME BLOCK CODE IN A MOBILE COMMUNICATION SYSTEM USING MULTIPLE INPUT MULTIPLE OUTPUT SCHEME

摘要

The present invention in a transmitter employing four transmit antenna in the first transmit antenna to the fourth transmit antenna , the information to be transmitted symbol streams to x ₁ x _{When 2} x ₃ x ₄ is input, the input Information symbol column of x ₁ x ₂ x ₃ x ₄ and x ₁ , x ₂ , x ₃ , x ₄ parallel conversion, and the converted information symbol streams in parallel x _{1 to} , x ₂ , x ₃ , x ₄ in the application to the pseudo orthogonal space-time block coding scheme between the first time interval the first through the transmit antenna and the x ₁ is sent, via the second transmission antenna and the x ₂ it is transmitted through the third transmit antenna x ₃ is sent, through a fourth transmit antenna x ₄ is being transmitted; In the second time period, through the first transmit antenna The transmission and, via the second transmission antenna is transmitted, the third through the transmit antenna is transmitted, through the fourth transmit antenna is has been transmitted; A third interval in -x ₁ is transmitted through the first transmit antenna in the liver, via the second transmission antenna -x ₂ is being transmitted, a third transmission via the antenna is x ₃ is sent, through a fourth transmit antenna x ₄ is being transmitted; In the fourth period of time is through the first transmission antenna The transmission and, via the second transmission antenna is transmitted, the third through the transmit antenna is transmitted, through the fourth transmit antenna is is encoded so that the transmission.
