ABSTRACT:
A coding technique for achieving a maximum diversity gain in a wireless communication system having a transmitter for transmitting data on a fading channel through a plurality of transmit antennas and a receiver for receiving the data through a plurality of receive antennas. In the coding technique, P mth-order sub-rotated vectors {right arrow over (r)}iare generated by constellation-rotating an Lth-order input vector {right arrow over (x)} including a plurality of input symbols modulated in at least one modulation scheme. m pth-order sub-vectors {right arrow over (u)}iare generated using the sub-rotated vectors {right arrow over (r)}i. Codeword matrices Ai({right arrow over (u)}i) are generated by performing orthogonal space-time block coding on the sub-vectors {right arrow over (u)}iand then transmitted through the transmit antennas.
