GUIDANCE DEVICE AND GUIDANCE METHOD

摘要

A method is disclosed that includes measuring, during a measurement period, values corresponding to noise and interference signals received from a channel. The measurement period coincides with a period when no signal is transmitted on the channel. The method also includes determining one or more thresholds based upon the measured values. Second signals that correspond to a message are received on the channel. The message includes an indicator having a number of possible states. A value is determined corresponding to the indicator based upon the second signals. One of the possible states is assigned to the indicator of the received message based upon the one or more thresholds and the determined value.
