Phase tracking in Bluetooth receivers using Extended Kalman Filtering
Ahmad Nsour, Alhaj-Saleh Abdallah, Mohamed Ali Zohdy · 2013
This paper investigates applying Extended Kalman Filter (EKF) to non-coherently estimate the phase of Gaussian Frequency Shift Keying (GFSK) modulation scheme in Bluetooth receivers. The paper examines the performance of Extended Kalman filters for Additive White Gaussian channel noise (AWGN) with IEEE802.11 coexistence. Both technologies operate in the unlicensed 2.4GHz Industrial Scientific Medical (ISM) Band. Experimental results for Extended Kalman Filter for Gaussian channel are provided.
