Abstract :
The extending orthogonal space-time block code is constituted by identical orthogonal space-time block code (OSTBC). However, the channel fading coefficient of each branch of each OSTBC is not taken into consideration. For this problem, an improved extending orthogonal space-time block code is proposed. Analysis shows that the system performance is enhanced, and the computational complexity is also greatly reduced with only a few bits increasing of feedback information. Simulation supports the conclusion.
