Constellation-rotating orthogonal space-time block coding technique |
摘要 |
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 m<SUP>th</SUP>-order sub-rotated vectors {right arrow over (r<SUB>i </SUB>are generated by constellation-rotating an L<SUP>th</SUP>-order input vector {right arrow over (x including a plurality of input symbols modulated in at least one modulation scheme. m p<SUP>th</SUP>-order sub-vectors {right arrow over (u<SUB>i </SUB>are generated using the sub-rotated vectors {right arrow over (r<SUB>i</SUB>. Codeword matrices A<SUB>i</SUB>({right arrow over (u<SUB>i</SUB>) are generated by performing orthogonal space-time block coding on the sub-vectors {right arrow over (u<SUB>i </SUB>and then transmitted through the transmit antennas.
