Abstract

Due to the problem that the capacity, bit ratio error and other performance index of MIMO system will deteriorate if antenna has stronger correlation, a feasible algorithm based on power control strategy is proposed. The new algorithm analyzes the influence of correlation on system capacity, then uses signal strength as switch strategy between MIMO and SISO system. This makes the system more stable even though in the stronger correlation situation. Simulation proves that the new algorithm is feasible and valid.
