This paper investigates the power allocation schemes for MIMO systems.An effective power allocation method for ZF/MMSE detected MIMO systems is then proposed.The method is designed to minimize the overall systems BER performance without pre-diagnalizing the MIMO channels using precoding.Compared with conventional power allocation schemes using SVD
the proposed method reduces the required feedback information.Simulation results show that this method effectively improves the BER performance.Moreover
the performance of this new method is also close to that of conventional precoded MIMO systems.
