Detection performance of simple timing synchronization schemes for frequency-hopped Bluetooth networks

This letter describes two adaptive timing synchronization schemes for a sho rt-ranged Bluetooth system in the partial-band noise environments. One esti mates the variance of the partial-band interference, which is utilized for the trigger threshold value of the inquiry scan and page scan slates, while second is designed using the scaled partial correlation value for the conn ection state. Numerical results show the proposed synchronization algorithm s are robust to the partial-band noise interference and of low complexity, which is suitable for a low-cost personal area network (PAN).
