Channel estimation and DC-offset compensation schemes for frequency-hopped Bluetooth networks

This article is concerned with a Bluetooth receiver with the channel estimation and DC-offset estimation. Each of the Bluetooth devices in the connection state knows the access codes used in the ad-hoc networks, which is utilized as a reference signal for the parameter estimation. The proposed estimators can be implemented without degradation of frame and spectral efficiency thanks to using the access code specified for the Bluetooth system.
