Stability Control of Power Adaptation in Wireless Communication System

The adaptive power adjustment technology can significantly enhance the adaptive ability for environment and electromagnetic compatibility of wireless communication system, which can save a lot of power. However, the bit error rate (BER) performance of system may be unstable when the environment changes rapidly. To improve the BER stability of wireless communication system with adaptive power adjustment, this paper introduces a state feedback controller with integrator to the power control in the system. Theory and simulation shows that the BER can be quickly stabilized at the target value when the system is subjected to a sudden interference.
