Abstract Transmission optimization for Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) broadcast channel with power-limited constraints is analyzed in this paper. Applying different optimization rules, two different transmission strategies are proposed. One is Optimal Space Distance Dirty Paper Coding(OSD-DPC), the other is Max Signal to Noise Ratio Dirty Paper Coding (MSNR-DPC). Numerical results show that proposed schemes have the similar performance to the optimal schemes and are capable of improving the system capacity and performance with power-limited constraints.
