Abstract :
A phase rotation precoding is proposed for MIMO system to reduce interference caused by transmit correlation. The optimal rotation phases are designed based on maximize the infimum of the set of effective error vectors´ norm. Simulation results show the validity of the proposed scheme, which, in the same conditions, improves reliability compared to the other phase rotation precoding scheme.
