MIMO is a key technology in the fourth generation cellular mobile communication system. Because of channel reuse, it may bring with serious co-channel interference (CCI). In order to reduce such interference, an improved distributed power control algorithm has been proposed. The exponential iteration has been taken in this algorithm, whose convergence speed is much faster than traditional arithmetic iterations. Moreover, in order to improve its robustness, the previous power in iterations has been added in current power iterative equation as a weighted feedback. In addition, this algorithm has been extended into multi-user MIMO cellular communication system. Compared to traditional algorithms, simulation results show that its iterative convergence rate is faster and its efficiency function is more efficient.
