APPARATUS AND METHOD OF PERFORMING A DECIMATION ON A SIGNAL FOR PATTERN DETECTION

The present application relates to a receiver for performing a decimation on a signal for pattern detection and a method of operating thereof. A frequency-domain decimator component and a pattern detector component arranged at the receiver are provided. The frequency-domain decimator component is coupled to at least one antenna to receive an input sequence of samples of the signal received at the at least one antenna. The frequency-domain decimator component is further configured to apply an anti-aliasing filter and to decimate the input sequence. The frequency-domain decimator component is further arranged to output the input sequence filtered and decimated as output sequence. The pattern detector component is coupled to the frequency-domain decimator component to receive the output sequence. The pattern detection component is further configured to perform a pattern detection based on cross-correlation values in frequency domain between the output sequence and predefined patterns.
