Abstract

Several industries are developing innovative devices with integrated Bluetooth technology to enhance user experience. Gaussian Frequency Shift Keying (GFSK), a special case of Continuous Phase Modulation (CPM) schemes, is the modulation scheme chosen for achieving basic data rate of 1Mbps with Bluetooth receivers. In this paper, we apply the Extended Kalman Filter (EKF) to non-coherently estimate the phase of GFSK modulation scheme in Bluetooth receivers. The paper examines the performance of Extended Kalman filters in the presence of Non-Gaussian impulsive noise with IEEE802.11 coexistence. Both technologies operate in the unlicensed 2.4GHz Industrial Scientific Medical (ISM) Band. Mean Square Error (MSE) was used as a measurement for the performance. Experimental results obtained for Extended Kalman Filter for Non-Gaussian noise are provided.
