Abstract :
The effect of the fast time varying channel on Almouti space-time block coding (STBC) scheme is analyzed in high speed mobile environment, and an improved scheme is proposed. Simulation results show that performance of the proposed method is much better than that of the Almouti STBC scheme when the vehicle speed is greater than 350 km/h.
