Method of and apparatus for detecting the presence of data in a received signal by monitoring the spread of values to synchronize receiver |
摘要 |
A receiver is synchronized to a signal and the presence of data in the signal is detected by responding to the signal to derive indications of the amount of time shift necessary to achieve synchronization between the receiver and signal. The receiver is adjusted to be in synchronization with the signal in response to the time shift indications. A measure of the spread of values of the time shift indications is derived. The presence of data in the signal is flagged in response to the spread of values being less than a threshold value.
