ABSTRACT:
A method of detecting a silent frame at a mobile station in a GSM transmission is disclosed. The method comprises first receiving a data burst intended for the mobile station. Then, a signal-to-interference-and-noise ratio (SINR) is determined for the data burst. If the SINR is below a predetermined threshold, then the data burst is determined as from a silent frame.
