Abstract:
A pattern detection circuit for performing pattern detection on input signals from a communication terminal, includes a frequency domain transformer that transforms input signals into frequency domain signals; a frequency extractor that extracts frequency components of the frequency domain signals; and a pattern detector that performs the pattern detection on the input signals based on cross-correlation values in frequency domain between the extracted frequency components and predetermined patterns.
