1. A method for space-time coding in a wireless system comprising M transmission antennas, the method comprising:

  • a transmitter of the wireless system generating an orthogonal matrix for signals to be transmitted by the transmitter;

    the transmitter of the wireless system generating a coefficient matrix corresponding to the orthogonal matrix according to at least one of the formulas;

    ( h 1 * h 2 *

    h M *
    )




    and



    M

    m = 1 M




    h m

    2




    ( h 1 * h 2 *

    h M *
    )
    ,
    wherein hm includes channel status information from the mth transmission antenna to a receiver; and

    the transmitter of the wireless system generating a transmission matrix according to the orthogonal matrix and the coefficient matrix.
