Abstract:
A system and method for classifying an input signal suspected of being a wireless LAN signal. Bursts are isolated based on an analysis of an average power signal that is derived from the input signal. A correlation-based test is performed to determine if the input signal contains a Barker code typical of DSSS transmissions. Another correlation-based test is performed to determine of the input signal contains a long training sequence typical of OFDM transmissions. The results of the two tests are used to classify the input signal as being DSSS, OFDM or neither.
