Abstract:
The present invention relates to a method of simultaneously performing packet detection, symbol timing acquisition, and carrier frequency offset estimation in parallel using multiple correlation detection and a Bluetooth apparatus using the same, in which the Bluetooth apparatus receiving a frequency modulated signal includes a frequency demodulating unit converting the received signal into a similar amplitude modulated signal; and multiple correlation detectors generating multiple correlation indices from the converted signal, on a basis of an access address received from a link layer and a plurality of carrier frequency offset search windows. According to the present invention, since packet detection, symbol timing acquisition and carrier frequency offset estimation are simultaneously performed in parallel in the relatively long access address reception interval instead of the short preamble signal reception interval.

Claim (Index 6):
The apparatus according to  claim 1 , further comprising a packet detector determining that packet detection is performed when the multiple correlation indices are equal to or greater than a threshold value.
