This paper presents a novel and costeffective method to be used in the optimization of the Gaussian Frequency ShiftKeying GFSK at the receiver of the Bluetooth communication system. Theproposed method enhances the performance of the noncoherent demodulationschemes by improving the Bit Error Rate BER and Frame Error Rate FERoutcomes. Linear, Extended, and Unscented Kalman Filters are utilized in thistechnique. A simulation model, using Simulink, has been created to simulate theBluetooth voice transmission system with the integrated filters. Results haveshown improvements in the BER and FER, and that the Unscented Kalman FiltersUKF have shown superior performance in comparison to the linear Kalman FilterKF and the Extended Kalman Filter EKF. To the best of our knowledge, thisresearch is the first to propose the usage of the UKF in the optimization ofthe Bluetooth System receivers in the presence of additive white Gaussian noiseAWGN, as well as interferences.
