Abstract :
A new precoding technique is proposed for STBC-VBLAST hybrid scheme in this paper. In principle of minimizing pair-error probability, we design the precoding matrix of this system using the features beam molding algorithm. This proposal takes advantage of CSI to reduce error rate and increase capacity. Simulation results show that this algorithm could achieve remarkable effects, especially in low constellation dimension.
