A study of power allocation strategy for amplitude-limited MIMO system
幅度受限MIMO系统的功率分配策略研究

Power allocation strategy for amplitude-limited MIMO system is studied and a new power allocation method is proposed. In this new method, nonlinear distortion caused by amplitude limiting is taken into account to improve the transmission quality. Simulation results also show that when the amplitude of transmit signal is large, the performance of traditional water-filling method will degrade obviously while the new method could provide better performance.
