ABSTRACT:
A repeater is configured so as to detect feedback oscillation conditions by detecting a gain parameter, and responding to the detected gain parameter by reducing the gain when the loop gain approaches unity. When used in a framed shared channel wireless communication systems, feedback oscillation conditions the loop gain of the repeater may be adjusted so as to permit operation of the repeater outside of the oscillation range. The invention is particularly useful when the repeater is used in a framed shared channel wireless communication system.
