Abstract
A new method of measuring co-channel interference for mobile communication systems is proposed. In this method, the carrier envelope is sampled, and signal-carrier-to-interference-carrier ratio (CIR) is calculated by signal processing. The circuits for measurement are composed of an envelope detector, an analog-to-digital converter, and a microcomputer. Theoretical and experimental evaluations of measurement errors are examined, and the method is proved to be promising. Using this method, the signal-to-interference ratio of up to 20 dB is measured, within 2 dB error for fading frequency of less than 80 Hz.Keywords
