Abstract :
In order to improve the reliability of VBLAST in block fading channel, phase rotation precoding is proposed. Through phase rotation of the modulated signals at the transmitter, the burst decoding error is changed into random error at the receiver, which can be corrected easily. So the system performance is enhanced. Simulation results demonstrate the validity of the proposed scheme.
