    摘要: Disclosed is a mobile communication system using a Multiple Input Multiple Output (MIMO) scheme. A transmitter of the mobile communication system, generates a unitary space-time matrix to correspond to a codeword if the codeword to be transmitted in a first time interval is input, multiplies the unitary space-time matrix by a first final transmission matrix denoting signals transmitted in a second time interval before the first time interval, thereby generating a second final transmission matrix denoting signals to be transmitted in the second time interval, and transmits signals corresponding to the second final transmission matrix through a plurality of transmit antennas in the second time interval.

    摘要: Disclosed is a differential space-time block coding apparatus with a high transmission rate in a wireless communication system employing multiple transmit antennas and a method thereof. The differential space-time block coding method includes the steps of, when elements of a transmission matrix B43v are transmitted in a predetermined block (a vth block) through a predetermined transmit antenna at a predetermined time, modulating a symbol Sv of inputted binary data to a symbol Sv+1, creating a matrix S44v+1 in a block (a (v+1)th block) following the predetermined block by substituting the modulated symbol for the matrix P44, and then, in order to perform a differential encoding function, multiplying the matrix B43v by the matrix S44v+1 so as to calculate a new matrix B43v+1 to be transmitted in the (v+1)th block.

    摘要: A method for transmitting to one cell a frame including broadcast channels in a cellular wireless communication system in which a base station supports a plurality of physical channels corresponding to the broadcast channels. The base station generates the frame and transmits the generated frame to a mobile station. The frame includes separate broadcast channels for the respective physical channels. A position, in the frame, of a first broadcast channel for a physical channel capable of supporting a mobile station having the worst channel state is fixed in all of transmission frames. The first broadcast channel includes positional information of the remaining broadcast channels except for the first broadcast channel. The mobile station detects only an address of a broadcast channel for a physical channel allocated thereto from the first broadcast channel among broadcast channels belonging to the frame.
