Patent ID: 6993100

Claim:
A burst detection system for detecting a burst in an incoming signal comprising: a signal strength change detector for determining strength changes in the incoming signal; signal strength detection logic for determining if a change in signal strength of a predetermined magnitude has occurred; a pattern detector for monitoring patterns of symbols in the incoming signal to determine if a predetermined pattern is present; a burst detector for signaling a detection of a burst if the signal strength change detection logic determines that a signal strength change of predetermined magnitude has occurred and the pattern detector determines that a predetermined pattern of symbols is present; a signal strength indicator for indicating the strength of the incoming signal; a short-term signal strength change detector for determining, responsive to the signal strength indicator, short-term changes in signal strength, and a long-term signal strength change indicator for determining, responsive to the signal strength indicator, longterm changes in signal strength; wherein the signal strength detection logic is configured to determine, responsive to the short-term and long-term signal strength change detectors, if a short-term change in signal strength of a predetermined magnitude has occurred, and a long-term change in signal strength of a predetermined magnitude has occurred; a signal strength indicator for indicating the strength of the incoming signal, and the short-term and long-term signal strength change detectors respectively determine short-term and long-term changes in signal strength responsive to the indication of signal strength provided by the signal strength indicator; wherein the short-term signal strength change detector is configured to determine A n , a current moving average of M samples of a n , the indication of signal strength provided by the signal strength indicator, and B n , a previous moving average of M samples of a n , where M is a non-negative integer.
