ABSTRACT:
An apparatus for controlling a gain of a transceiving device in a terminal for a communication system is disclosed. A memory stores predetermined thresholds for level-by-level gain controlling. A signal intensity detector detects an intensity value of a received signal. Comparators compare the received signal intensity value with thresholds predetermined according to the current state. A state detector detects a gain level for the current state according to the comparison results provided from the comparators. A controller updates the current state according to the detected gain level, controls a gain of the transceiving device according to the updated current state, and sets thresholds corresponding to the updated current state in the comparators.
