| 摘要 |
The present invention relates to a method for detecting the presence of an OFDM signal in a received signal wherein said received signal is down converted into baseband and subjected to a passband filtering corresponding to a band of interest before being sampled. The thus sampled signal is subjected to a second filtering for eliminating at least one interfering line in the band of interest. The presence of an OFDM signal is detected if the signal filtered by the second filtering is cyclostationary.
