Abstract  Abstract

A method for transmitting data via multiple antennas by modulating data to be transmitted into a plurality of modulated symbols encoding each pair of modulated symbols from among said plurality of symbols in accordance with a transmission diversity scheme to result in a plurality of N by N matrices with each N by N matrix corresponding to each pair of modulated symbols generating a M by M code matrix comprised of the plurality of N by N matrices orthogonally spreading the M by M code matrix to generate an output matrix generating a plurality of row-permuted matrices by exchanging at least one pair of rows in the output matrix and transmitting the symbols in the plurality of row-permuted matrices via a plurality of antennas by using either a space time transmission diversity scheme a space frequency transmission diversity scheme or a combination of a space time transmission diversity scheme and a space frequency transmission diversity scheme.
