Abstract
An apparatus and method are described in which a corrected signal-to-interference ratio (SIR) is determined in a cellular telephone receiver. First the estimated signal strength at the receiver is measured, then the estimated interference level is measured. The signal strength and the interference values are separately corrected in accordance with an algorithm. Thereafter, a corrected SIR value is obtained by dividing the corrected signal strength and the corrected interference values.
