Abstract
An apparatus and method for measuring a Signal-to-Interference-plus-Noise Ratio (SINR) by controlling a residual gain in a high speed packet access system are provided. The apparatus includes a gain controller for measuring an intensity of a signal outputted from a residual gain controller, for outputting a gain control signal for controlling a gain of an interval of a preset gain resolution of a radio frequency integrated circuit according to the intensity of measured signal, and for outputting a residual gain value for controlling a residual gain less than the preset gain resolution, wherein the radio frequency integrated circuit gain-controls a signal inputted according to the gain control signal, and the residual gain controller multiplies the gain-controlled signal by the residual gain value to compensate the residual gain.
