Abstract
Disclosed herein are a Bluetooth signal receiving device and method for receiving a Bluetooth signal. The Bluetooth signal receiving device includes a discriminator circuit and a correlator circuit. The discriminator circuit generates a baseband signal by performing frequency shift demodulation on a received signal, and generates a frequency proportion signal having a value proportional to the frequency of the baseband signal. The correlator circuit detects a packet assigned to the Bluetooth signal receiving device by comparing the frequency proportion signal with an access address received from a link layer. The Bluetooth signal receiving device may detect a packet, assigned to the Bluetooth signal receiving device itself, by using access address information of a link layer.
