Adaptive control method and apparatus and the repeater system output signal

Adaptive control method and apparatus and the repeater system output signal to a communication technical field, the quality of the adaptive control method by detecting the output signal of the repeater, the signal quality calculation after characterizing the signal quality value after the signal quality threshold comparison, and dynamic power control is achieved according to the comparison result. The present invention combines techniques and echo cancellation adaptive signal quality monitoring and power adjustment, the repeater avoid self-excited at the same time, to ensure that in the case where a signal quality above a predetermined threshold maximum output power, facilitate the discharge linear expansion station coverage, improve repeater coverage effect, and ultimately the formation of self-consistent work patch point between the repeater network.
