1. A space-time code used for a transmitter to transmit a plurality of data symbols from a transmitter to a receiver in a multi-input multi-output (MIMO) system having multiple transmit antennas and multiple receive antennas, the space-time code comprising:

  • a square code word matrix for transmitting an amount of data symbols corresponding to a product of the number of transmit antennas and a spatial multiplexing rate during one code block period, a row index of the code word matrix indicating combined signals transmitted through different transmit antennas and a column index of the code word matrix indicating time slots; and

    wherein in a code block, the average number of data symbols allocated to each transmit antenna at every time slot is equal to the spatial multiplexing rate and at every time slot, the data symbols allocated for each transmit antenna are combined together and simultaneously transmitted through the corresponding transmit antenna, and each transmit antenna transmits a different set of data symbols from a time slot to another.
