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^th-order sub-rotated vectors {right arrow over (r_i are generated by constellation-rotating an L^th-order input vector {right arrow over (x including a plurality of input symbols modulated in at least one modulation scheme. m p^th-order sub-vectors {right arrow over (u_i are generated using the sub-rotated vectors {right arrow over (r_i. Codeword matrices A_i({right arrow over (u_i) are generated by performing orthogonal space-time block coding on the sub-vectors {right arrow over (u_i and then transmitted through the transmit antennas.
